The 20 jobs facing the heaviest losses in the next four years

As AI and automation continues to develop at speed, more and more research is looking at which industries really need humans - and which may not.

New analysis by analytics company Faethm by Pearson in partnership with technology company ServiceNow has predicted that almost 10 per cent of Australia's workforce - about 1.3 million people -will have to retrain by 2027 as automation continues to take over.

Here are the 20 careers facing the biggest job losses in that time.

Delivery drivers will lose the equivalent of 12,665 full-time jobs (a drop of 15 per cent).

Pharmacy sales assistant roles will drop by 13,290 (32 per cent).
