Australia has backed a crackdown on tourists who flout Indonesia's drug laws after Bali police said they would force travellers to undergo random urine tests at clubs and rave parties.

Bali drug squad chief Bambang Sugiarto plans to get Indonesian drug squad officers to force tourists, at random, to submit to the urine tests at social venues.

He says education campaigns have been run about Indonesia's drug laws. The next logical steps for officers trying to uphold those laws are random testing and raids, he says.

Foreign Minister Alexander Downer has backed the crackdown, which follows the recent series of Australian arrests including Sydney model Michelle Leslie.

Leslie was allegedly caught with two ecstasy tablets in her bag at a dance party in Bali. She could face 15 years in jail if she is charged and convicted of possessing the drug.

"I think the Indonesians are right to crack down on drug use in Indonesia and drug trafficking," Mr Downer told reporters in Adelaide.

"I support the Indonesian government - they have their own measures for doing this.

"I agree with the Indonesians in this respect, in that I think drugs are wrong."

Mr Downer said Australians should know the dangers of being involved with drugs in Indonesia, in the wake of the Schapelle Corby and Bali Nine drug cases.

"People should be absolutely vigilant in Indonesia or anywhere else for that matter," Mr Downer said.

"If they are going to travel abroad (they should be) making sure that they have no association with drugs whatsoever.

"These are the laws, there will not be special laws for Australians in Indonesia."

Mr Downer did not comment specifically on the plan to introduce random urine tests at Indonesian party venues.

The federal Opposition said Indonesia was within its rights to carry out random testing, but said the country must ensure police doing the work are not corrupt.

"If they believe they have a drug problem within their country then it lies entirely within their powers to take these sorts of measures," Opposition foreign affairs spokesman Kevin Rudd told Sky News.

"What we would also need to have some guarantees about is the probity of the police force undertaking these tests themselves to make sure that they are free from corruption or any other maleficence."

Mr Rudd also called for travel agents to be forced to issue travellers with government advisories warning about the penalties they face if caught with drugs overseas.

Airlines could also be asked to screen in-flight video warnings about penalties for criminal offences in different countries.

The recent spate of Australians arrested on drugs charges overseas highlighted the need for such warnings before travellers left Australia, Mr Rudd said.

"The government's response is that travellers can get it (warnings) online and/or at smart traveller portals at airports," he said in a statement.

"Our view is this does not go far enough.

"We call upon the government to consider requiring the travel industry to provide copies of relevant travel advisories at the point of booking."

But the government rejected the call, saying no number of travel advisories would be as effective a warning as the Corby case.

Mr Downer said there had been a 30 per cent increase in access to travel advisories in the past financial year.

"No number of travel advisories is going to provide as much publicity as the Schapelle Corby case did," Mr Downer said.

"Surely people have heard about the Schapelle Corby case and now the Michelle Leslie case - and knowing these cases they should not take these risks."

"The issue isn't whether people have access to travel advisories. There are lots of ways they can access travel advisories, through their travel agents, through the internet and kiosks in airports."
