Links to pornographic websites have been posted on the website of Family First Senator Steve Fielding.

The links, in Russian, were posted on a public forum section of the senator's website in February, but were not detected until a northern Tasmanian man alerted the ABC.

Senator Fielding wants the Australian Federal Police to investigate the links.

He says he is disturbed by the breach as some of the links are connected to Russian websites that involve children.

"From what I've been told - I haven't seen the sites that have been referred through to - they are sites that I don't think anyone should be really viewing or actually seeing," he said.

"We're gong to be referring it through to the Australian Federal Police."

Senator Fielding says the breach strengthens his case for the tighter regulation of internet content.

"Look I don't know what drives people to do this sort of thing," he said.

"It is disturbing. But I suppose this is the reason why we do need to have some sort of classification, some sort of filtering, and I do know that is controversial."
