The party-branded Australian-made aircraft will take off from Caloundra Airport on Thursday morning.
"I am thankful to now have a plane, as this will enable me to visit people around the state and interstate, including those in small remote communities," Ms Hanson said.
The aircraft is emblazoned with the party logo and features a cartoon of the now national chairwoman waving an Australian flag.
It also features the tagline "Fed Up Tour".
Ms Hanson said the plane's first official journey would be to Rockhampton on Friday, ahead of a Reclaim Australia rally on Sunday.
The group campaigns regularly against "sharia law, halal tax and Islamisation".
Supporters stood against racism and championed the right to free speech, Ms Hanson told a Brisbane rally in April.
It came after she lost her bid for the seat of Lockyer in January's state poll by fewer than 200 seats.
It was the 12th election she had contested in her controversial political career.
More recently, she changed the party's name back to Pauline Hanson's One Nation.
It has a new motto to match: "Never give up, we won't."
