Four people were caught attempting to sail from Byron Bay to Cairns, without exemptions from border closure.
Since last weekend the Queensland border has been closed to people travelling from NSW unless exemptions are sought and granted.
Maritime safety officials arrested the four people on Friday, discovering none of them had a border exemption, Nine News reported.
Each party member now faces a $4000 fine and will be required to pay for a mandatory hotel quarantine stay of 14 days.
The Queensland Government declared that on August 8, after a rise in community transmission of the virus since mid-July, the entire NSW state and the ACT were considered to be COVID-19 hotspots.
On July 3rd Victoria was declared a hotspot.
Anyone who has been in a hotspot for the past 14 days without special permission is not permitted to enter Queensland and is expected to stay in quarantine for two weeks after entering the territory.
