That's correct. Neither the department nor the government has had any formal discussion about possible increases to the carbon price. The 2050 target is a formal target. The government's emissions reduction plan doesn't have a prescriptive pathway to achieving all of those reductions. It very clearly says that the current plan is a plan to move the economy in that direction and to start taking some of the early actions needed to get to 2050. It doesn't include all of the measures needed.
