content: There are few from Philippines:https://www.ebay.com.au/itm/274180164892https://www.ebay.com.au/itm/402343858098https://www.ebay.com.au/itm/402022076770Not sure why they are so expensive, A$125 to A$380 and the shipping is over A$150. I remember this scope was common at the AM/FM radio assembly line in 1980s.Have a holiday there and bring them back.

content: I see two for sale here in Japan, one for 1000yen the other for 2000yen.I could ship one to you. I also have the matching audio oscillator on my shelf if you want that.(there was a whole set of matching test gear available, it pops up here in Japan from time to time).Not sure if you can see it from Australia:https://auctions.yahoo.co.jp/search/search?p=CO-1303DI'll be back in Brisbane and Adelaide over christmas too, failing postage and if I have space in my luggage.You'd have to check the mains voltage thing though, I don't know if they are voltage selectable with a switch or wire links on the transformer etc.
