Qantas confirmed all passengers had remained in Sydney overnight.
”Customers will be provided accommodation and re-accommodated onto the next available flight.
”We apologise for the disruption to their journey and thank them for their understanding.”
The airline added no passengers were impacted, though one cabin crew member was transported to hospital “for further medical checks as a precautionary measure”.
This isn’t the first time a flight has had to abruptly turn around because of a particular smell onboard.
Last year, an Air New Zealand flight between Nelson and Auckland was grounded at Hamilton Airport due to the smell of gas.
In 2018, Indonesian airline Sriwijaya Air was grounded over the pungent smell of durian fruit.
The airline admitted it was carrying more than two tonnes of the smelly fruit and said the smell would dissipate once the plane took off.
A journalist from Indonesia’s Antara news agency was also on board and reported that some passengers had arguments with staff that nearly ended in physical blows.
