I think that he means gameshows retired in the last 5 or so years. You are right though, Sale was a big hit in Australia. My grandma was actually on Sale in 1985 and won everything. Unfortunately I don't have the video but I do have a list of prizes containing what she won.
Speedboat (worth $15,000+)
Dining Room Setting (worth $8,000+)
Musical Instruments (Guitar, Piano and Drumkit) (worth $18,000+)
Grandfather Clock ($6,000+)
Camping Trailer ($12,000+)
Trip to Canada ($16,500+)
BMW 750i Sedan ($60,000+)
Cash Jackpot ($162,000)
She has sold the majority of the prizes due to taxes and stuff, sold the drumkit off to me, and kept the trailer in her backyard. In total she won approximately $297,500
