A sell-out crowd of around 24,000 is expected for Saturday's third Ashes Test between Great Britain and Australia, even though the Kangaroos are 2-0 up in the three-game series.
That means the current record of 23,678 for the Town v Liverpool FA Cup third-round tie in 1999 is ready to fall.
Even the restricted view seats at the front have now been snapped up as the Lions look to restore some lost pride.
All three Tests have been sell-outs - the first two were at Wigan and Hull - and delighted Giants chairman and Huddersfield Town owner Ken Davy believes it's a clear sign of the health of the British game.
"While it's disappointing we couldn't beat the Australians, it's fantastic we've attracted three sell-out crowds," he said.
"Rugby League is in a good state of health right now, with the Ashes series coming on the back of a great Super League season.
"And this all bodes well for the future.
"But I also believe attracting a record McAlpine crowd this weekend is also a sign of the positive atmosphere there is running through the whole town on the professional sports front.
"In the last few days Town have secured a great win over leaders Hull in front of a season's best crowd.
"Then there was an outstanding turn-out of over 800 at the stadium to watch the Giants juniors taking on the Penrith Panthers Under 18s last night.
"And now we hear the news that a record crowd is expected for the third and final Ashes Test.
"I do genuinely believe these are all signs which show that the underlying work that is taking place behind the scenes right now is slowly starting to bear fruit."
Mr Davy was among the crowd of 807 who watched the Giants Academy go down 50-24 to Penrith last night.
That may appear a heavy defeat, but the Panthers are rated by many as the best junior side in world rugby, and the Giants chairman believes the result was no disgrace.
"Penrith are a champion side back in Australia, so we always knew we would be in for a tough time," he said.
"But I thought the young Giants gave an excellent account of themselves and wore the claret and gold colours with pride.
"Losing to Penrith is no disgrace, and on last night's evidence I believe the future of the Giants lies in good hands."
Super League squad men Ben Feehan (ankle) and Rikki Sheriffe (shoulder), who were both in action last night, suffered injuries, but were able to report for training today.
