But heres the larger issue-if they dont check your bag through-you 100% will NOT make this connection. Guaranteed 0%. I hate to break it to you but post-Covid the lines for INTL arrivals between 6-9am in SYD are ABYSMALLY long. It could easily be an hour from the time you land to get the time you get your bag and then youd have to get in the long ques at baggage exit.

DL ops at SYD will close the DL flight at exactly 1 hour prior to departure. If you arrive at a transfer desk or a check in desk after that time you will be denied. Since you wont be checked in, even if Garuda do send your bag (which is looking more doubtful) that connection will be nearly impossible on separate tickets unfortunately. DL doesnt have a pre-customs check in or transfer desk at SYD I dont believe.

Honestly, youre going to need to be prepared to buy a new DL ticket at a walk-up price or id find a way to arrive SYD a day early.
