The postal service says it needs to fill 1600 permanent and fixed term jobs across the country, and another 3300 casual jobs before Christmas, to deal with a record surge in online shopping.

There are vacancies in every state and territory, with workers needed in parcel, mail processing and customer service teams, as well as posties who drive vans, trucks and motorcycles.

Australians are sending and receiving parcels in volumes not seen since Christmas.

"At the moment, every day feels like Christmas at Australia Post and we're on the lookout for people to join us and help deliver and process record volumes across the country," executive general manager of people and culture Sue Davies said.

"We're proud of the outstanding efforts of our people working hard across the country who keeping delivering and supporting communities through challenging circumstances."

The recruitment drive is Australia Post's second in less than a month, after it called for 4000 new staff at the end of August.

Earlier this month, the mail service temporarily paused parcel pick ups from online retailers in the locked down jurisdictions of NSW, ACT and Victoria for three days to process a backlog.

Last year ,Australia Post set aside $190 million to cover voluntary redundancy payments over three years as it grappled with an expected $500 million full year loss.
