This seems to be the best distillation I have found.

GPS tracking & multiple COVID-19 tests for VI tourists
- when tourist arrivals commence December 1, 2020
ROAD TOWN, Tortola, VI – Tourists who arrive in the Virgin Islands (VI) from December 1, 2020, will be required to meet strict requirements, including GPS tracking and multiple instances of COVID-19 testing, before they are allowed unrestricted access to the territory.
The measures were announced tonight, Monday, October 26, 2020, by Premier and Minister of Finance, Hon Andrew A. Fahie (R1) in a statement broadcasted across radio, television and social media.
COVID-19 PCR test before arrival to territory
The Premier said that to come to the territory, persons would have to agree to the terms and conditions before boarding their flight and will have to obtain a negative Polymerase Chain Reaction (PCR) test at least 5 days ahead of travelling.
“These terms and conditions include periods of quarantine at approved accommodation, Polymerase Chain Reaction (PCR) testing, medical travel insurance that includes COVID-19 coverage, subscription to a contact tracing system through their mobile phone, and in some cases using a wearable device, and bearing the costs associated with these measures,” Premier Fahie said.
He said approval for the travel will first have to be done via an online portal called BVI Gateway as entry into the VI will be exclusive to air travel via the Terrence B Lettsome International Airport from December 1, 2020.
GPS software & second COVID-19 test on arrival
“On arrival at the Terrance B. Lettsome International Airport, the traveller will do a PCR test and we will ensure that the visitors have installed the contact tracing software on their mobile phones.”
Following that step, the Premier said tourists would then be directed to approved transportation which will take them to their approved accommodation for isolation.
According to Premier Fahie, in the first four days, travellers would be required to remain within the compound of their accommodation and to avoid or minimise contact with others outside of their party, as well as to keep their movement to a minimum.
Third COVID-19 test after brief quarantine
Following that initial quarantine, on the fourth day, the traveller would be required to take another PCR test and once the result is negative, they would be allowed isolated movement to designated places. These would be locations that are not high traffic or high risk.”
He said the locations are being coordinated by the Environmental Health Department and other Government agencies and the establishments will be notified.
Fourth COVID-19 test for free movement
A final PCR test would be administered on Day 8 and once this test also returns negative, the traveller would be able to move within the Territory without limitation, the leader of Government Business detailed.
