However, the pigs and goats were removed during the early 20th century, and rabbits were exterminated by 1988.

Reforestation of Norfolk Island pine on Phillip was assisted in the late 1980s by a C130E Hercules from 37 Sqn RAAF Richmond. Record crops of Norfolk pine seeds were collected and aerial seeded on Phillip Island by the Hercules aircraft.
