The Queensland border bubble has expanded with residents from 41 postcodes in Northern NSW now allowed to travel into the sunshine state.

Major delays are to be expected as more than 150,000 residents from NSW can now make the journey north and Queenslanders are now also permitted to travel to far Northern NSW.

Those travelling into their neighbouring state will no longer have to quarantine for 14 days at their own expense, granted they have not been to a Covid-19 hotspot within the last two weeks.
