Queensland's transport minister hopes another 15 per cent fare hike won't deter people from catching public transport, urging commuters to look at the new services the increase will fund and “give us a go”.

The state government is trying to soften up commuters for this Monday's fare hike on the southeast Queensland bus, train and ferry network, a move it insists is crucial to allow the continued rollout of new and more frequent services.

Fare hikes for southeast Queensland train, bus and and ferry services kick in from Monday.

Transport Minister Annastacia Palaszczuk said extra bus services to be introduced over the next six months would see a further 140,000 seats become available for passengers each week.

These would include 45,000 extra weekly seats from a “back to university” package to be rolled out in February, and 95,000 on other new services in mid-2012.
