No.
12 Squadron was the first Vengeance-equipped RAAF unit to see combat.
After converting to the dive bomber, the squadron was used on routine patrol and search-and-rescue tasks off the coast of the Northern Territory.
On 18 June 1943, twelve Vengeances from the squadron, escorted by six No.
31 Squadron Bristol Beaufighters, were dispatched to attack two villages on Selaru island in the occupied Netherlands East Indies that were believed to be housing workers engaged in constructing an airfield.
This operation was successful, and all the dive bombers returned to base.
In July 1943 the squadron began moving from Darwin to Merauke in Netherlands New Guinea, where it was to operate as part of No.
72 Wing.
A party of 270 ground crew arrived at Merauke early that month, but little of the infrastructure needed to support the unit's aircraft was ready.
As a result, No.
12 Squadron's Vengeances and air crew were stationed at Cooktown, Queensland, from where they conducted anti-submarine patrols and escorted shipping.
The aircraft were redeployed to Merauke over the course of September, and began regular patrol duties on the 28th of the month.
No.
12 Squadron's only combat during this deployment occurred on 9 October 1943, when a Vengeance exchanged machine-gun fire with a Japanese Aichi E13A reconnaissance aircraft.
The Vengeances proved unsuited to the maritime patrol tasks they were assigned while at Cooktown and Merauke.

The commander of the Allied Air Forces in the South West Pacific, Lieutenant General George Kenney, requested in late August 1943 that the RAAF dispatch a squadron of dive bombers to New Guinea for use against pinpoint targets in the Huon Gulf area.
No.
24 Squadron was selected for this role, and its 18 Vengeances were rushed to Tsili Tsili Airfield before crew training was complete.
Little of the squadron's supporting equipment was dispatched as it was intended that the deployment would be temporary.
After arriving at Tsili Tsili on 2 September, the squadron flew its first combat mission on the 7th of the month.
This operation was frustrated by bad weather, and the aircraft almost ran out of fuel on their return flight due to difficulties in locating their airfield.
An attack the next day was successful.
On 18 September, No.
24 Squadron dispatched 14 aircraft as part of an attack on Japanese positions near Finschhafen in preparation for a landing by Australian Army forces.
The squadron destroyed a Japanese radio station on the Tami Islands near Finschhafen area on 21 September.
It provided support for Australian Army units involved in the Huon Peninsula campaign during late September and October.
This included playing a significant role in halting a major Japanese counter-attack during early to mid October.

The lack of ground equipment complicated No.
24 Squadron's operations, especially as it took a long time for this material to arrive once a decision to retain the unit in New Guinea had been made.
As a result of equipment shortages and inadequate aircrew training, the squadron was not fully ready for combat until December; this greatly frustrated Kenney's deputy, Brigadier General Ennis Whitehead, who commented that "we have never gotten a mission out of that unit".
Some of the training deficiencies were due to the RAAF's practice of stationing operational training units in southern Australia, with the result that aircrew were unfamiliar with flying in tropical conditions.
During December, the squadron operated against Japanese positions on New Britain and New Ireland ahead of the American landings in western New Britain.

In September 1943, Kenney asked the RAAF to provide a mobile strike force for offensive operations in New Guinea.
The RAAF decided that the force should comprise a wing equipped with Vengeance aircraft and another wing of fighters to escort the dive bombers.
No.
77 Wing was formed as the dive bomber unit in what was designated No.
10 (Operational) Group, and comprised Nos.
21, 23 and 24 Squadrons as well as service and medical units.
The other major element of the group was No.
