The Giants have bid farewell to Perth after a three-day extravaganza that drew hundreds of thousands of people into the city.

The Little Girl and the Diver have now embarked on a boat journey in the Swan River, never to return.

The Giants slept in Langley Park overnight before a gargantuan performance leading up to their embarkation.

The snores of the sleeping Giants gave way to a pulsating didgeridoo as day three of their special visit got under way before massive crowds.

The rousing, extended playing echoed around the park and across the river as the Little Girl rested in the arms of her protective uncle, as the rest of the band came to life and the Lilliputians started work for the last time in Perth.

The pair reunited yesterday in a heart-warming end to a day which saw crowds of 400,000 turn out to see them.

After spending the last two days searching for each other in the CBD, the Little Girl Giant and the Diver Giant finally found each other last night, embracing at Langley Park about 7pm.

Many in the crowd appeared emotional as the six-metre Little Girl Giant was lifted into the air to greet the 11-metre Diver Giant against a picturesque Perth skyline.
