Can I trade GBP/AUD with them??

https://uppertrade.world/ 

UpperTrade is not a regulated or licensed broker for traders even though it states offers that look good to be true.

UpperTrade claims to be owned by Tetris Group LTD, a company registered in the Commonwealth of Dominica with a registration number 2021/IBC00019. But please be informed that Dominica currently has no forex regulator that issues licenses for forex trading or regulates entities engaging in forex trading.

More importantly, the Romania Financial Supervisory Authority (ASF) issued a warning against both Tetris Group LTD and UpperTrade for being not authorized by the Financial Supervision Authority to provide investment services and activities according to the provisions of Law no. 126/2018 regarding financial instruments. You can check the full warning from here.

The truth is, UpperTrade is not overseen by any regulators. That means your personal data or your funds in this broker are unsafe and cannot be protected by any law. We would recommend traders stay away from unregulated brokers like UpperTrade and trade with licensed brokers.
