News Corp is refusing to explain exactly how it will spend taxpayers' money more than six months after the Turnbull government granted Foxtel $30 million.

While a funding agreement has been drawn up and signed, Foxtel and its parent company remain tight-lipped about which sports have benefited from the government handout. The broadcaster was eligible for the first instalment – worth $7.5 million – last month after the government signed off on its 2017-18 "strategic roadmap".

Foxtel has been airing AFL Women's League games as well as women's softball in recent weeks. However, it is unclear whether taxpayer funds were used to obtain these broadcast rights.

A Foxtel spokesman declined to comment and instead referred questions to News Corp, which owns a 50 per cent stake in Foxtel. A News Corp spokeswoman refused to specifically detail which sports benefited from the government's first $7.5 million grant but said Foxtel's commitment to women's and niche sports was evident.
