Update Wednesday: Over 50 visitors from across Victoria joined Nhill Aviation Centre staff at the museum's reopening on Saturday.
In a statement, volunteers said the flight simulator was a highlight for visitors.
The opening hours remain the same this coming weekend.
Monday June 29: Have you been using lockdown to focus on some passion projects? So has a Wimmera tourist attraction.
The Nhill Aviation Heritage Centre's president Rob Lynch said a newly-painted plane will greet visitors when the centre opens this weekend.
"(Nhill engineer) Mick Kingwill has been working hard to have the Avro Anson plane ready in time for the reopening," he said. "He now has a name around the world for his restoration work."
"Mick is there every day around lunchtime and he said people have started to come back in to the aerodrome to have a look. People are starting to come back to the RV camping area right next to us. It would be great if the lockdowns didn't apply to this area too."
The centre closed soon after being one of the stops for light aircraft pilots, commemorating the 100th anniversary of cross country flight by doing one themselves, on March 21. Mr Lynch said in the time since, the committee had been working to keep the complex in top condition.
"Our committee is as enthusiastic as ever, it's given us a real boost to be able to reopen. Hopefully there will be some people there," he said.
Mr Lynch said also on display is the propeller from the second aircraft designed and built in Australia, 'Silver Wings'. It was built on a farm near Rainbow between 1919 and 1921.

The centre makes use of the site of a WWII RAAF training base. Over 12,000 young Australians trained as navigators, gunners and maintenance staff, to prepare for their roles in the conflict over five years.
The centre will open Saturday and Sunday 10am-4pm.
Hindmarsh shire to test visitors
Visitors to Nhill, Jeparit and Rainbow tourist attractions and caravan parks will will be required to have their temperature tested.
In a statement on Monday, Hindmarsh Shire Council announced it had secured thermometers from the state government. The attractions include Yurunga Homestead and the Wimmera Mallee Pioneers museum.

Director of Corporate and Community Services Monica Revell said the Aviation centre would likely also receive thermometers to test visitors once it opened.
"It's an infrared thermometer which you hold up against your forehead," she said. "Green indicates a normal reading and red indicates a high reading. If you have a high temperature you will be turned away, because that is one of the signs of COVID-19."
"If you are unwell, the shire encourages you to stay home."
