Police stopped the prime mover on Dumaresq Crossing Road at Texas late on Wednesday.
The 51-year-old woman was hiding behind the driver’s seat.
She and a 61-year-old man who was driving the truck were each issued with a $4003 infringement for failing to comply with the Queensland Border Direction.
They were also denied entry to Queensland.
Police stopped more than 180 heavy vehicles for COVID-19 health restriction compliance checks at three sites along the border.
Officers also conducted heavy vehicle road safety patrols, including roadside breath and drug testing.
Three drivers returned a positive drug test.
The traffic operation will run for several weeks and follows an investigation in Mackay last week where 16 Victorian carnival operators were found to be travelling around Queensland in breach of heath directions.
Each was fined $4003.
