In Kamtschatka La Perouse landed Monsieur Lesseps, who had accompanied the expedition as Russian interpreter, and sent home by him his journals and surveys.

Lesseps made a careful examination of Kamtschatka himself, and succeeded in passing overland thence to Paris, being the first European to journey completely across the Old World from the Pacific to the Atlantic Ocean.

La Perouse then proceeded to follow Cook by examining the coast of New South Wales, and to his surprise, when entering a fine harbour in the middle of the coast, found there English ships engaged in settling the first Australian colony in 1787.

After again delivering his surveys to be forwarded by the Englishmen, he started to survey the coast of New Holland, but his expedition was never heard of afterwards.

As late as 1826 it was discovered that they had been wrecked on Vanikoro, an island near the Fijis.
We have seen that Cook's exploration of the eastern coast of Australia was soon followed up by a settlement.
