The ACT Legislative Assembly will return today for the first of two consecutive sitting weeks.

Budget debate will dominate proceedings as the government looks to pass its 2019-20 budget through the Assembly.

Liberal member for Brindabella Andrew Wall will ask the government to commit to introducing laws he says will protect ACT businesses from "vegan vandals".

He wants the government to strengthen criminal trespass laws for all forms of "animal-related business", in line with those recently introduced in NSW, considered the toughest in the country.

Those laws mean anyone who illegally trespasses onto farming properties face an on-the-spot fine of $1000. Individuals can be fined up to $220,000 and $440,000 for groups and corporations.

The Morrison government has introduced federal laws that would impose up to a year in prison for using a carriage service to incite trespass on farms.

Those proposed laws have been criticised by the Law Council as having the potential to stifle debate.

"There should be no place in the ACT for vegan vandals who incite and commit crime," Mr Wall said.

"The ACT is home to a number of animal-related businesses including primary producers, wildlife facilities and research facilities that could be a potential target for this kind of illegal activity."

In other Assembly news, Labor backbencher Bec Cody will ask the Assembly to make a tripartisan statement in support of sex therapy and sex work under the NDIS.

She wants the Liberals, the Greens and Labor leaders to sign her motion and send it to the Prime Minister and the NDIS Minister.

Ms Cody wants the Assembly to acknowledge that, like everyone else, people with disability have sexual needs.

It comes after a recent Administrative Appeals Tribunal ruling that sex therapy should be considered necessary and reasonable support for a NDIS participant.

The NDIS will appeal that decision.

Meanwhile, Labor backbencher Michael Pettersson will call on the government to consider increasing light rail services during peak periods.

Opposition spokeswoman for transport Candice Burch also wants the government to provide an updated weekend timetable that reflects the availability of weekend bus drivers by Wednesday of each week.

There have been thousands of weekend bus cancellations since the new network was launched in late April, due to insufficient drivers.

Deputy Opposition Leader Nicole Lawder will call on the government to recognise the opposition to buses along Anketell Street in Tuggeranong.
