I'm a consultant in the R&D Tax space. The press release relates to an advanced finding, which is an advanced approval of R&D activities. It does not however guarantee approval for the amount of expenditure they would be claiming. A tax refund of that size would naturally attract the attention of the Australian Tax Office(ATO). The press release is also dated before they could submit their tax return to obtain a 14/15 refund. A key problem with the press release is that there is now a $100million cap on how much expenditure they can claim in a financial year, so theoretically their maximum benefit would be $45million.
$120million in software R&D is a very large spend in Australia for one year, Google Australia for example claims about $40-$50million in R&D spend each year. Atlassian and some of the larger banks would claim a similar amount. I have not heard much about DeMorgan before, however if it all checks out they would be one of the most significant powers in the Australian tech space.
