A Victorian minister who used a taxpayer-funded car to chauffeur his dogs to a home he forgot to tell parliament he owned insists he won't resign.
The opposition wants Corrections Minister Steve Herbert investigated over his "mistakes" - but he sits on the Privileges Committee, which would do the investigating.
Mr Herbert was forced to apologise for using his car to chauffeur dogs Patch and Ted more than 120 kilometres between his homes in Parkdale and Trentham while he was at work.
Late on Thursday the beleaguered MP also updated his register of interests to declare ownership of the home in Trentham, his principal place of residence.
"I thought it was on the register of interests. As soon as I found out it wasn't I made sure it was put on there," Mr Herbert told reporters on Friday.
When asked if he would resign, Mr Herbert replied: "No."
Prime Minister Malcolm Turnbull said he was surprised Mr Herbert still had his job.
"I'm amazed that he's still there but it seems an extraordinary thing to do," he told 3AW.
"We have to remember that these resources that are available to us are for work, not for transporting dogs or anything else."
But Premier Daniel Andrews said while his corrections minister had "stuffed up" he should not have to resign.
"I spoke to him this morning and I've made it clear that he needs to get these affairs in order," Mr Andrews told reporters in Brisbane.
"He's been a minister that's been at the centre of some very significant reforms and changes, some really good and important work, and he's very keen, as am I, to continue with that,."
Opposition leader Matthew Guy told reporters there were grounds for Mr Herbert to be referred to the Privileges Committee.
Mr Herbert has been on the Legislative Council committee since April 2015.
"He couldn't even and wouldn't even announce how many times he put the dogs in the back of the car and took them to Trentham," Mr Guy said.
"My understanding is this has been a regular activity every sitting week since he's been a minister, so if you add that up over the last two years... it's at least 30-odd times."
But Mr Herbert said the dogs travelled in the car by themselves "a couple of times, from Parkdale to Trentham".
"There were other times of course when I couldn't leave the dogs alone so they came with me in their cages," he said.
Mr Herbert said he was working with bureaucrats to determine how much petrol money he should pay back to the parliament.
On Thursday he blamed his "tough job" for his error in judgment over the dogs.
