MONA founder's secretive betting business in court over ‘rip off' by employees
Hired as a data analyst in 2017, O'Toole was meant to be working within the confines of American basketball and baseball. But the anonymous email suggested he had secretly installed a computer code to extract other information from the company's systems, which he then used to place his own bets.
The tip-off triggered the Supreme Court action to uncover the scope of what Data Processors calls 'a dishonest and fraudulent design' to use company data for personal profit.
Around the time of the search of O'Toole's apartment, he was sued for breaching duties of confidence arising from his employment. The list of defendants later expanded.
Data Processors also sued former employee Joel Caley for allegedly writing an application known as the Jupyter Code, which was then installed by O'Toole.
'The data accessed and transmitted by the Jupyter Code … are in the nature of betting probabilities generated by the plaintiff's algorithms, including betting probabilities relating to horse racing,' Data Processors contended.
In their court filings, Caley and O'Toole said they wrote the code together.
A third employee, Michael Demos, was accused of accessing other betting odds data. The trio was said to have shared confidential information among themselves and with two non-employees, Kusuv Bhandari and Richard Zhang.
According to Data Processors, each member of the group used confidential information to place bets funded with their own money, as part of a rival syndicate.
Four of the defendants have admitted to some liability. Demos does not admit to what Supreme Court judge James Stevenson has called 'the critical allegations' but nor does he deny them.

What the group resists is the suggestion that Data Processors suffered losses and is entitled to compensation or damages – setting the stage for the ongoing court fight.
The most well known of the company's directors is Walsh, who signs off on the financial records while also presiding over the Museum of Old and New Art in Hobart. The former mathematics student wrote in his autobiography that he founded MONA in 2011 'to absolve myself from feeling guilty about making money without making a mark'.
Ranogajec, who has served as a Data Processors director for the past 12 years, met Walsh in the 1980s, playing table tennis. The pair started card counting at the blackjack tables of Wrest Point casino in Hobart before later expanding into Keno and horse racing.
It was a 2008 court case that first provided an insight into the scale of their operation. When Ranogajec moved to bankrupt a former business partner, federal magistrate Rolf Diver asked him how much the gambling syndicate turned over each year.
'My guess would be $1 billion,' Ranogajec replied. Telling the magistrate his syndicate was known as the Bankroll Punters Club, he said 'customers that bet on our level number in the handful in the world'.
The Punters Club made headlines in 2012 when the ATO pursued syndicate members for about $600 million in taxes and penalties, arguing the club was a business rather than a hobby. The matter later settled out of court.
Ranogajec moved to London, buying a property in the world's most expensive apartment block, One Hyde Park, and now goes by the name John Wilson (after his wife, Shelley Wilson). Walsh said in 2022 that Ranogajec remained the leader of the syndicate.
In March, the NSW Supreme Court deferred a decision on whether to split the Data Processors trial into two hearings – one focused on guilt, the other on the extent of the financial damage to the company – until more evidence was served.

Too good to be true: Sydney exec testifies in $253m Perth fraud trial
The investors who entrusted him with more than a quarter of a billion dollars say Chris Marco held himself out to be an experienced businessman – a leprechaun who could take them to the pot of gold at the end of the rainbow. Only there was no pot of gold, prosecutor Steven Whybrow, SC, told the Western Australian Supreme Court, just a flimsy scheme kept afloat by the flow of funds being used to pay off old investors that was taking on water fast.

St George study sample pioneers Brazil magnet rare earths supply
St George Mining has achieved a significant milestone by delivering Brazil's first bulk rare earths sample to a Government backed project tasked with commercialising Brazil's sizeable rare earths endowment to create a magnet manufacturing facility. The MagBras project is a public-private initiative based in Minas Gerais, Brazil. The 30kg rare earths oxalate sample, derived from the company's 100%-owned Araxá project, marks St George as a frontrunner in Brazil's emerging rare earths supply chain. The Araxá project has a serious mineral resource estimate of 40.64 million tonnes (Mt) at a sizeable grade of 4.13 per cent total rare earths oxide. Notably it also has another resource dimension, with 41.20Mt at 0.68 per cent niobium pentoxide, making it potentially a world-class asset ideally positioned to meet growing global demand for both commodities. The MagBras project, supported by the National Service of Industrial Learning (SENAI) and the Minas Gerais Research Development Foundation (Fundep), aims to industrialise Brazil's vast rare earths endowment - the world's third largest – to reduce the nation's reliance on imported high performance magnets. Managed by the Federation of Industries of Minas Gerais (FIEMG), MagBras collaborates with rare earths developers such as St George and end-users, including automakers Stellantis and Iveco, to build an integrated magnet supply chain. St George's memorandum of understanding (MoU) with MagBras - signed last October - facilitates cooperation on research, development and potential supply of high-grade rare earths from Araxá for high-performance magnet production. The company is also exploring downstream partnerships in the US, where interest in Brazil's niobium and rare earths is surging. The US Government, under the Trump Administration, is pursuing a trade deal to secure Brazil as a key supplier of critical metals, driven by efforts to establish non-Chinese supply chains. St George says recent US Department of Defence support for American rare earths miner MP Materials by paying US$110/kg for combined neodymium-praseodymium (NdPr) highlights a shift toward pricing that fosters industry growth. Prineas says the company is seeing strong support in Brazil from government and industries to build a domestic supply chain for rare earths . St George's Araxá project is strategically located a stone's throw north of the massive niobium mine operated by Companhia Brasileira de Metalurgia e Mineração (CBMM). The two projects occupy the same Barreiro carbonatite complex, a geological formation known for hosting significant niobium and rare earths mineralisation. CBMM's operation primarily extracts niobium from pyrochlore, with rare earths present as secondary commodities alongside barium and thorium. The company supplies about 80 per cent of the global niobium market. That proximity potentially provides St George with access to established infrastructure and a skilled workforce, enhancing its overall development potential. St George is advancing its Araxá project with an extensive drilling program, including over 9000 metres of diamond drilling to infill and expand its known resources and associated mineralisation. Mineralisation currently remains open in all directions and the infill drilling aims to increase confidence in the resources and elevate existing inferred resources to indicated status. The project's high-grade mineralisation, which shows up to 8 per cent niobium pentoxide and 33 per cent TREO, underscores its potential as a global supplier. The company is keeping five drill rigs busy and expects its first assay results shortly. Meanwhile, ongoing metallurgical studies aim to optimise the flowsheet for rare earths production. Its collaboration with SENAI and FIEMG positions Araxá to contribute significantly to both local and global markets, particularly as geopolitical shifts drive demand for reliable, non-Chinese rare earths and niobium sources.

Australian farmers clap back at Donald Trump's claims US beef will flood the Aussie market
Australian cattle farmers have hit back at Donald Trump's claims American beef will 'flood' the market down under, but say they are concerned about biosecurity risks and failure to consult industry before agreeing to take more US imports. The red meat sector was blindsided last week when the Albanese Government confirmed it had relaxed restrictions on US beef imports — a move welcomed by the US President on social media, where he declared American producers would sell 'so much to Australia' and described their product as 'the safest and best in the entire world.' More than 99 per cent of beef sold in Australian pubs, supermarkets and restaurants is Australian beef, and industry believes the change will have little significant material impact on what Aussie consumers can buy on the shelf. The US president took to social media last week to welcome the controversial move, saying his farmers planned to sell 'so much to Australia', which was the 'safest and best in the entire world'. But farmers and other industry stakeholders Countryman spoke to said the US — Australia's biggest beef buyer — would struggle to compete with the strong domestic cattle industry. They said any US beef imports would likely be used in restaurants, fast food or pre-packaged meals, rather than on supermarket shelves. Rabobank RaboResearch Australia and New Zealand general manager Stefan Vogel said high prices and tight supply in the US would make it difficult for the industry to send a significant volume of beef to Australia in at least the next five years. The US' cattle herd is in a restocking phase after several years of drought. While the amount of beef coming into Australia from the US was unlikely to be significant, Mr Vogel said there could be a market for it. 'We may see some very specific product coming into the market, like a Texas steakhouse, bringing in US beef, rather than mass product,' he said. 'For now, we don't think this will be a gamechanger.' Australia shipped nearly 400,000 tonnes of beef worth $2.9 billion to the United States last year, with just 269 tonnes of US product moving the other way. Australia is the world's second-biggest beef exporter, behind Brazil, while the US is the second-biggest importer of beef, behind China. Western Beef Association chair Mark Thomas said there was a reason Australia was exporting record volumes of beef into America. 'They can't supply their own market, let alone supply ours,' he said. 'This (the imports) is actually a positive thing for Australian beef because removing the inability for America to export into Australia... removes an excuse that America has to not allow Australian beef.' Australian Pork Limited boss Margotr Andrae said Australia 'must not allow trade pressure to override the science, animal welfare standards and food security'. It was a view echoed by National Farmers' Federation president David Jochinke, who said 'tariff negotiations' should be removed from any conversation on biosecurity. '(It) should be dealt with separate from any tariff negotiations,' he said. The cattle industry has also lashed out after receiving no consultation during the final stages of the review. Cattle Australia chief executive Will Evans said the organisation had not seen any detail of the science-based assessment prior to the announcement and was now reviewing the DAFF paper. The group is also concerned that the rules applied to Australian beef exports into the US will not be reciprocated for incoming US product. It plans to call for an independent scientific panel to review how the decision was made. 'We believe an independent scientific assessment is a sensible and prudent way forward. This must occur before imports commence,' Mr Evans said. 'There is simply too much at stake when it comes to Australia's world-leading biosecurity status not to get a second opinion. 'Given the Minister's confidence she should have no issue appointing an independent panel to take the highest level of precaution in protecting the Australian beef industry.' The lack of consultation has sparked criticism that the decision was rushed to appease Mr Trump as he considered slapping more than the existing 10 per cent tariff on all Australian imports announced in April. The US is Australia's largest beef customer, importing 400,000 tonnes worth $US4.2 billion ($6.3b) last year. A prolonged drought has shrunk the US herd to its lowest level in 75 years, sending domestic beef prices to record highs. Despite the longstanding ban on transhipped beef, US born and raised beef has continued to enter Australia, with imports reaching 270 tonnes in 2024-5, the highest since the mid 1990s, according to Episode3's Matt Dalgleish. He said the sheer scale of Australia's 1.4 million tonne annual beef exports made biosecurity paramount. WA Pastoralists and Graziers Association president Tony Seabrook also raised concerns about the traceability of beef imported from the US, saying Foot and Mouth Disease would 'ruin our industry overnight'. 'How the hell would we know where it came from? You've only got to take it out of one box and put it in another, and you'll never know where it came from,' he said. Mr Seabrook labelled the timing 'coincidental' amid tariff talks and accused the Government of making the decision 'without due consultation' with industry. Australia banned beef imports from the US in 2003 after the, mad cow disease, or fatal neurological disease bovine spongiform encephalopathy, was discovered in American cattle. The blanket ban was lifted in 2019, but restrictions remained on beef was sourced from Canada or Mexico and slaughtered in the US. But Red Meat Advisory Council chair John McKillop said industry felt 'relaxed' about the decision 'as long as the science is there'. 'You always get a bit suspicious when you think that things have been pushed through, and maybe they have… or at least expedited because of the pressure from the US. 'But as long as the science is there… then as an industry, we're relaxed about it.' Mr McKillop said a claim by the Minister on Thursday that the US and Australian supply chains were 'equivalent' wasn't accurate because America doesn't have lifelong traceability of stock. 'It's not quite correct. They don't have the same systems as us. We have full lifetime traceability in Australia and have had for 20 years through the Livestock Identification scheme. 'The US has failed to implement such a system.' The Australian Lot Feeders' Association Christian Mulders said Australia had 'rightly undertaken' an assessment after America's 2020 request and was satisfied with the government's assurance on US controls. Mr Mulders said that 'so long as it meets our import requirements' he wasn't opposed to imports, adding that the association was a free trade advocate. Myalup beef producer and WAFarmers livestock president Geoff Pearson also he would 'like to see the detail in the science' and questioned the politics behind the move. 'You could call it a political pathway to negotiation into the tariff and the first introduction Albanese has got with Trump,' he said.
