The man claimed he was flying from Townsville in far north Queensland to Brisbane on Monday afternoon.
The photo he shared on Twitter shows every seat filled with passengers sitting well within the minimum 1.5m of each other and not wearing face masks on the one hour and 45 minute flight.
‘This is a on a flight from North Queensland to Brisbane today for work. What kind of social distancing is this?’ the passenger captioned the photo.
The passenger insists the photo was taken on Monday and also shared a photo of his boarding pass to back up his claim.
Daily Mail Australia has contacted the passenger for further details.
A Qantas spokesman told Daily Mail Australia the airline was unable to verify whether the photo was taken on Monday’s flight.
He added social distancing had been happening by default on most flights due to low patronage.
‘The average load factors on our aircraft have been very low, with most flights around 30 per cent full, so social distancing has been happening by default,’ the spokesman said.
‘The weekend saw some flights that were much busier, which was the case on this particular flight.
The spokesman added there have been no known cases anywhere in the world of people contracting coronavirus on board a plane.
Qantas recently slashed the number of flights between Brisbane and Townsville by more than 60 per cent, from 36 flights a week to just 14.
The national carrier has suspended all international flights and more than 50 per cent of its domestic routes until at least the end of May.
Qantas has also significantly reduced its in-flight entertainment and food and beverage service due to new government restrictions and a dramatic decline in travel demand.
‘We’ll no longer be serving meals on domestic or regional flights. Our crew will continue to offer a complimentary bottle of water and a snack on these services,’ the Qantas website states.
The in-flight entertainment and wi-fi services, including the onboard magazine, have also been temporarily halted.
Qantas and Virgin Australia could be on the verge of receiving a bailout package from the federal government to continue operating domestic flights during the crisis.
The funding agreement is reportedly nearing completion and is worth tens of millions of dollars.
