ACT Opposition Leader Mark Parton used his budget reply speech to outline several policy commitments that the ACT Liberals would pursue if elected in 2028.

Key proposals included introducing 50-cent fares across Canberra's bus and light rail network, creating dedicated anti-graffiti teams to rapidly remove vandalism in the city centre, and establishing a legislated charter of budget responsibility aimed at improving fiscal discipline, transparency and intergenerational equity.Parton argued that the ACT government's latest budget asks residents to pay more while receiving fewer services.He said the territory's financial position would require more than a single term of government to repair.

The Liberal leader also pledged to recriminalise methamphetamine possession, reversing the ACT's drug decriminalisation reforms supported by Labor and the Greens.According to Parton, the current approach has failed to adequately address community harm caused by the drug.

Additional commitments included expanding endometriosis and pelvic pain treatment services at Canberra Hospital through a more integrated model of care, and introducing legislation focused on suicide prevention.

Parton reaffirmed the Liberals' previous election pledge to expand Canberra's bus fleet and provide stronger public transport service guarantees.

The opposition also criticised the government's plans for extending light rail to Woden, describing the project as insufficiently costed and lacking firm commitments.

Parton signalled that a future Liberal government would review spending on consultants, travel and administrative costs, seeking savings of between 10 and 25 per cent.

Chief Minister Andrew Barr rejected the proposals, arguing that recriminalising meth would revive ineffective policies and that the 50-cent fare plan would worsen the ACT's finances.

Meanwhile, ACT Greens leader Jo Clay highlighted the Greens' influence on recent budget changes and called for broader structural economic reforms, including greater taxation of wealth.
