Not Mark, I think it's more likely he will go and help Wayne and Penny keep an eye on the government finances and deliver this surplus.

I mean think about it a bit little more - he has a very good understanding of cashflow and how to make it happen, amazing with promises, expenses, delivering things on time, speaking to the public and voters etc

And he could also get involved with the next 2020 summit.
Maybe throw his hat in the ring (is this the lingo on Pitt Street in Sydney??) and put forward a case to chair it!
