At this stage it’s quite difficult to say. The relevant agencies will still be collating their requirements for submission to the Australian Migration authority.
The migration authority will then use this information (which will include an indication of demand) to create the 2017 – 2018 Skilled Occupations list.
I expect that we will have a better idea in the next couple of months. With that said, medical jobs are still being advertised with 457 sponsorship on offer so I would expect most medical roles to still be in demand.
