For the Pacific, RAAF and RNZAF operated under their own nationality.
Yes Pips, the RAAF and RNZAF operated under their own nationalities or flags in the PTO - that's a given fact. But their nationalities (or goverments) operated strictly under the colonial interests of the larger Commonwealth umbrella. They were not as independent as you think. The RNZN is one example.

History of the Royal New Zealand Navy
Pre-World War I
The first recorded maritime combat activity in New Zealand occurred when
Dutch explorer Abel Tasman was attacked by
Māori in war
waka off the northern tip of the
South Island in December 1642.
The New Zealand Navy did not exist as a separate military force until 1941.
[1]The association of the
Royal Navy with New Zealand began with the arrival of Lieutenant (later Captain)
James Cook in 1769, who completed two subsequent journeys to New Zealand in 1773 and 1777. Occasional visits by Royal Navy ships were made from the late 18th century until the signing of the
Treaty of Waitangi in 1840.
William Hobson, a crucial player in the drafting of the Treaty, was in New Zealand as a captain in the Royal Navy. The signing of the Treaty of Waitangi made New Zealand a colony in the
British Empire, so the defence of the coastline became the responsibility of the Royal Navy. That role was fulfilled until
World War I, and the Royal Navy also played a part in the
New Zealand Wars: for example, a gunboat shelled fortified Māori
pā from the Waikato River in order to defeat the
Māori King Movement.
World War I and the Inter-War period
In 1909, the New Zealand government decided to fund the purchase of the
battlecruiser HMS New Zealand for the Royal Navy, which saw action throughout
World War I in Europe. The passing of the
Naval Defence Act 1913 created the
New Zealand Naval Forces, still as a part of the Royal Navy, and from 1921 to 1941 the force was known as the
New Zealand Division of the Royal Navy. The first purchase by the New Zealand government for the New Zealand Naval Forces was the
cruiser HMS Philomel, which escorted New Zealand land forces to occupy the German colony of
Samoa in 1914.
Philomel saw further action under the command of the Royal Navy in the
Mediterranean Sea, the
Red Sea, and the
Persian Gulf.
Between World War I and
World War II, the New Zealand Division operated 14 ships, including the cruisers
HMS Achilles and
HMS Leander, and the minesweeper
HMS Wakakura.
World War II

HMNZS Achilles
HMNZS Achilles participated in the first major naval battle of
World War II, the
Battle of the River Plate off the
River Plate estuary between
Argentina and
Uruguay, in December 1939.
Achilles and two other cruisers,
HMS Ajax and
HMS Exeter, were in an operation that forced the crew of the German
pocket battleship Admiral Graf Spee to scuttle her rather than face the loss of many more German seamen's lives. This decision apparently infuriated
Hitler. The
Achilles moved to the Pacific, and was working with the US Navy when damaged by a Japanese bomb off
New Georgia. Following repair she served alongside the British Pacific Fleet until the war's end.
HMNZS Leander escorted the
New Zealand Expeditionary Force to the Middle East in 1940, and was then deployed in the
Mediterranean Sea, the
Red Sea, and the
Indian Ocean. The
Leander was subjected to air and naval attack from
Axis forces, conducted bombardments, and escorted convoys. In February 1941, the
Leander sank the Italian auxiliary cruiser
Ramb I in the Indian Ocean.
In 1943, after serving further time in the Mediterranean, the
Leander returned to the
Pacific Ocean. She assisted in the destruction of the
Japanese cruiser Jintsu and being seriously damaged by torpedoes during the
Battle of Kolombangara. The extent of the damage to
Leander saw her docked for repairs until the end of the war.
As the war progressed the size of the RNZN greatly increased, and by the end of the war there were over 60 ships in commission. These ships participated as part of the British and Commonwealth effort against the Axis in Europe, and against the Japanese in the Pacific. They also played an important role in the defence of New Zealand, from German raiders, especially when the threat of invasion from Japan appeared imminent in 1942. Many merchant ships were requisitioned and armed for help in defence. One of these was
HMNZS Monowai, which saw action against a Japanese
submarine off
Fiji in 1942. In 1941-1942, it was decided in an agreement between the New Zealand and United States governments that the best role for the RNZN in the Pacific was as part of the
United States Navy, so operational control of the RNZN was transferred to the
South West Pacific Area command, and its ships joined
United States 7th Fleet taskforces.
In 1943, the light cruiser
HMS Gambia was transferred to the RNZN as HMNZS
Gambia.
In November 1944, the British Pacific Fleet, a joint British Commonwealth taskforce, was formed, based in Sydney, Australia. Most RNZN ships were transferred to the BPF, including Gambia and Achilles. They took part in the Battle of Okinawa and operations in the Sakishima Islands, near Japan. In August 1945, HMNZS
Gambia was New Zealand's representative at the
surrender of Japan.
