I apologize for bumping...just my 2cents.
Had an experience hiring a customs broker.
Was easier for them to clear my goods because they knew what they're doing already.
Was really tough to start a new life since there is a pandemic going on right now. It took them more than 2 weeks now.
I use ACC Fremantle customs brokers to help me and I apologize, guys, I know that this topic is very old, but maybe my answer will help someone in the future.
