Israel Folau is looking at hitting back at Rugby Australia's termination but the tax man is set to provide an obstacle for the 30-year-old's legal hopes.
Folau's backers were looking to financially assist the fallen Wallabies star if he took Rugby Australia to the Supreme or Federal Court in a bid to overturn his axing.
But the Australian Taxation Office (ATO) has told revealed to The Sunday Telegraph they will be monitoring donations to the former star with reports it could be funnelled through his church The Truth Of Jesus Christ Church, in Kenthurst, in order to get a tax deduction.
Reports suggest Folau's legal costs could be upwards of $1 million.
"Endorsed income tax exempt organisations are required at all times to comply with their governing rules and apply their income and assets solely for the purpose for which they are established," an ATO spokesman told The Sunday Telegraph.
