As the next federal budget looms, there's been fresh attempts to re-insert the tax on tampons into the GST debate.

Over 34,000 people have signed an online petition calling on federal Treasurer Joe Hockey to remove the tax in the upcoming GST review.

The communityrun.org campaign was launched by Sydney University student Subeta Vimalarajah, who questions the fairness of what she says amounts to taxing a bodily function.

"Because the government doesn't consider the tampons and pads we're forced to buy every few weeks necessary enough to be GST-free," Ms Vimalarajah writes in her petition.

"On the other hand, condoms, lubricants, sunscreen and nicotine patches are all tax-free because they are classed as important health goods."

The hashtags #StopTaxingMyPeriod and #BloodyOutrage have been spreading the message on social media.

Ms Vimalarajah says the government should give greater consideration to women's reproductive health and hygiene.

"People who get periods don't buy pads and tampons for pleasure, so why are we forced to fork out an extra 10 per cent every two, three, four weeks?" she asks.

"Taxing Australians for getting their period isn't just sexist, it's fundamentally unfair."

It's not the first petition calling for the scrapping of the tax on tampons, a 2013 campaign garnered over 43,000 signatures.

The government is currently taking submissions for a GST re-think, which would feed into its policy preparation process for the 2016 election.
