MYKI will proceed under the Baillieu government, but treasurer Kim Wells yesterday refused to say how much more Victorians will pay for the bungled smartcard beyond the $1.35 billion already committed.

Speaking at the release of the budget yesterday, Mr Wells said the government was negotiating to make sure Victorians got the best deal possible for myki. ''When we [the Baillieu government] take ownership of myki, we are going to make sure it works,'' he said.

But he refused to give any detail on what the Baillieu government expected to spend on retaining myki.

Mr Wells' first budget revealed that the government's promise for armed guards on every railway station in Melbourne after dark had blown out by $31 million.

It will now cost $212 million, up from an expected $181 million during last year's election.
