The Heritage Weekend is known internationally, having been a subject in historical vehicle magazines of Britain and other countries.
"It's amazing what has been achieved from such humble beginnings," said Graeme McMillan, past president of the Warwick Veteran and Vintage Vehicle Club, organising body of the Heritage Weekend.
And humble they were, "the weekend was born 1995, as an opportunity for local enthusiasts to roll their vehicles, machinery and motors out of their sheds and have a bit of fun".
In a few short years to year 2000, the Heritage Weekend was famous throughout Queensland and NSW and provided a line up of hundreds of displays, the large majority working, for the enjoyment of the endless crowds rolling up to the event.
Recent years have provided the historical machinery feast with plenty of challenges weather wise, the 2011 Heritage Weekend actually cancelled due to local flooding issues, and the 2012 and 2013 events affected by rain.
"There's not a lot we can do about the weather," Mr McMillan said. "We'll be pushing on to create a special event for the public and those involved, and quietly confident of blue Southern Downs skies on the Australia Day weekend."
The historical machinery extravaganza, arranged by the group of dedicated WVVVC volunteers from around the central and Southern Downs, takes pride of place in this part of the world, fittingly on the Australia Day weekend, and now boasts exhibit numbers in the thousands, countless visitors and international fame.
While historical machinery will roll into Allora from around Australia, the contribution from local vehicle and machinery restorers gives accurate recollections of the Southern Downs historical past.
