Football commentator Simon Hill has opened up fractures in Australia's code wars by suggesting the NRL and AFL should have their funding cut.

Hill was speaking to Adelaide radio station 5AA on Wednesday after Australian football's 'Black Tuesday', which saw Brisbane Roar lose 6-0 to Ulsan Hyundai and Western Sydney go down 5-1 to Shanghai SIPG in the Asian Champions League.

The Fox Sports presenter was bullish when explaining that football in Australia and the country's international sports reputation would suffer if money continue to be invested into 'dead end sports'.

"You’re not going to like me saying this, and I know some of your listeners won’t, but we’ve got to stop investing government money, state and federal, in internationally dead-end sports like AFL and rugby league," Hill said.

"I’m sorry but it’s the truth. If you want to be competitive in international sports you have to invest in them.

"If you just want to be world champions in sports that only feature two or three other nations, or not even that in AFL, then great, but don’t call yourself the greatest sporting nation on earth if you’re not going to compete internationally.

"There is a correlation between investment and success… per capita we’re not investing enough in football in this country.

"We can’t even get $5 million… that’s the problem. It’s a big issue. This is the brutal reality of international sport."
