Hi, we are traveling from Canada back to Australia via LAX later in Feb and struggling to work out whether there are testing requirements to be met in the US. We plan to meet the PCR test requirement for re-entry back into Australia (no more than 72 hours prior) but do we also need to meet the reduced time requirement in the US of no more than a day beforehand? Searched various sites but could not find an answer. Obvious answer is to find a quick turnaround PCR test at YVR but would like to know whether there is an exemption or not from the normal USA testing requirement. We fly out of YVR, into LAX then onto MEL that same evening and stay air-side the whole time. Thanks
