The size of Pulau Bukom is about 1.45 km2 (0.56 sq mi).

This companion islet is currently connected to Pulau Ular and Pulau Busing by reclaimed land, making the three of them appear as one large island on satellite imagery.

Security passes are issued only to personnel working on the island.

The ferry operator is Tian San Shipping.

The security checks are very tight, and no unauthorized person is allowed to enter the island.
