Around 200 Australians in Ireland are seeking to return home but have found themselves unable to do so due to restrictions on international arrivals in Australia.
Passengers say the cap on international arrivals, which was introduced last month, has led to airlines rationing seats and prioritising business class tickets.
The Australian embassy says it has fielded over 100 calls in the last week in relation to this issue. It is inviting Australians seeking to return home to register with them online.
The embassy says it is providing assistance to its citizens on this issue but pointed out that the airlines involved operate independently of the Australian government.
