The Belmont resident celebrated his Sandover Medal win in style, winning the count by one vote ahead of South Fremantle's Aston Hams.
Tropiano's parents Tony and Anita watched the count online, with Aidan expecting to poll well after an outstanding season that saw him win the Butcher Medal as Perth's best and fairest.
When their son was announced the winner, Tony and Anita went to bed, got two hours sleep, and then drove the more than 500km journey from Mullewa to Perth.

"They just said they are in the car and will meet us in the morning and I am very thankful for it."
The count was one of the most thrilling Sandover counts in recent history.
Tropiano led for most of the night, but was challenged by Hams and Subiaco's Sam Menegola.
Hams led with just one round to go, with Tropiano taking the win by polling four votes on the second-last vote read out on the night.
The 23-year-old's win came despite Perth winning just two games and coming last on the WAFL ladder.
The night proved a double celebration as it was also Tropiano's 23rd birthday.
He said people couldn't understand how special it was to wear the Sandover Medal.
"It was a massive honour – you don't understand how much it means to a person," he said.
