Married At First Sight star Tamara Joy has revealed how she was allowed to travel overseas during the coronavirus pandemic.

The 32-year-old reality star jetted from Australia to the UK five weeks ago despite international borders being 'closed'.

Tamara told Daily Mail Australia on Tuesday she was granted permission to travel overseas because of a work permit.

'I applied for an exemption as you can't get past the Australian borders without an exemption to leave, and it was granted quite quickly,' she said.

'I was approved for an existing working contract and left five weeks ago. What also helped was the fact I have no intention to return to Australia anytime soon and it's at my own risk.'

Tamara continued: 'I had to provide all correct documentation to support this and prove I could support myself being away from Australia for a certain period of time.'

'I have gone through the correct channels and did a lot of research to find out how to make my situation work,' she concluded.

People can travel to and from other countries that are not low-risk if they receive exemptions.

These are not automatic exemptions; they have to be granted by the Commissioner of the Australian Border Force.

Exemptions are granted if travel is part of the response to the Covid-19 outbreak, if travel is for your business or employer, to receive urgent medical treatment, if you're travelling on compassionate or compelling grounds, for urgent or unavoidable personal business or if travel is in the national interest.

If you want to leave Australia to travel on a return ticket, you may be able to go if your travel is for more than three months - if you have a 'compelling reason'.

Studying overseas is noted as acceptable evidence, as is travelling to provide care for a sick family member.
