Australia Post says there is no mail backlog despite a two-day strike by postal workers.
The Australian postal workers' union claims thousands of staff took part in strikes on Tuesday and Wednesday, threatening Christmas deliveries for the first time in 30 years.
But Australia Post says 80 per cent of workers were on the job yesterday, and with the help of casuals and administrative staff, the mail went out as usual.
Postal workers are continuing with industrial action in Western Australia, South Australia, the Northern Territory and Tasmania today, despite posties returning to work in other states.
Employees have gone back to work in New South Wales, Queensland and the ACT in what they say is a goodwill gesture to deliver Christmas mail.
The postal workers union says it was forced to take action after trying to negotiate with Australia Post for the past three years for better working conditions.Australia Post is trying to minimise the impact of a walkout by thousands of union members over a new workplace agreement.
