This is a Sydney, Australia transportation card, an Opal card. Sydney has five public transportation options: trains, metro, buses, light rail (tram), and ferries. The rechargeable card that can be used on all transportation options is the Opal Card. When purchasing an Opal card for the first time at a station, etc., a minimum of A$40 (equivalent to 4400 yen) is required. Also, the minimum recharge amount is A$20 (equivalent to 2200 yen). Although Opal cards with no balance are sold on Mercari, if you buy a card with no balance, you won't be able to pass through the ticket gates, and you'll need to recharge at least A$20. In this regard, this card has a remaining balance of A$10.4, so you can pass through the ticket gates with just a tap, without needing to recharge. If you want to refund the amount charged to the card, you can only do so if you have an Australian bank account. If a Japanese person who doesn't have an Australian bank account buys a card and only uses buses and trains for a small amount, they will lose a lot of money. Also, if you arrive late at night or early in the morning, the station ticket office is closed, so you can't buy a card at the ticket office. However, if you have this card, you can pass through the ticket gates just by tapping it. There are machines near the ticket gates to recharge your Opal card. You can recharge with a credit card or cash. - Sydney Transportation Card: Opal Card - User Type: Adult - Balance Check: A$10.4 Thank you for viewing. #Australia #Sydney #sydney #opalcard #transportationcard #opal #travel #SydneyAirport #overseas #opal #tourism #businesstrip
