From the govt press release:
Starting September 26, the boarding requirements and quarantine arrangements for inbound persons from overseas places or Taiwan will be adjusted as follows:
- Presentation of a negative nucleic acid testing report prior to boarding will no longer be required. Instead, a declaration of the negative result of a self-arranged rapid antigen test (RAT) conducted within 24 hours prior to the scheduled time of departure should be made via the online Health & Quarantine Information Declaration of the Department of Health.
- Boarding requirement of having completed vaccination for Hong Kong residents will be lifted. Non-Hong Kong residents aged 12 or above will still be required to be fully vaccinated or have obtained a medical exemption certificate before they are allowed to board a flight for Hong Kong.
- "Test-and-go" arrangement will be implemented at the Hong Kong International Airport, i.e. inbound persons will not be required to wait for the test result at the airport after undergoing specimen collection for the nucleic acid test. They can take public transport or self-arranged transport to return to their home or their hotel of choice.
- Quarantine arrangement upon arrival at Hong Kong will be changed to "0+3", i.e. no compulsory quarantine will be required. There will be three days of medical surveillance during which inbound persons are free to go out but are obliged to comply with Amber Code restrictions under the Vaccine Pass, followed by a four-day self-monitoring period, making it a 7-day observation period in total.
- Nucleic acid tests at community testing centres, mobile testing stations or other recognised institutions on Day 2, Day 4 and Day 6 (the day of arrival is Day 0) will be required upon arrival at Hong Kong, supplemented by daily RATs from Day 1 to Day 7.
- For inbound persons who are tested positive by nucleic acid tests or RATs, their Vaccine Pass will be converted to a Red Code. Their isolation arrangements will be aligned with that for local cases.
