Some Australian data I picked up around 14 years ago from a now defunct website. I would note that it is not mine, with all spelling left in its original state, and that I don't have the means to attribute the author, whoever it might be.

By 1939 Australia had a significant capability to produce small arms, small arms ammunition (Rifles, Brens, Vickers), Mortars and ammunition, 18 pdr ammunition and began tooling for 25pdr production and ammunition, Naval gun ammo to 8". About 50% of machine tools were made in Australia, and 50% imported, with the later number droping.
Early 1940 Australia begins supplying munitions to the Indian Army (who lacked production capabilities?) and to British forces in the SEASIA/Middle east.
By Dec 1941 Austraia had 7 Small Arms Ammunition Factories, 10 Small Arms Factories, 6 Explosive making factories, 5 cartridge case factories, 2 ordonance factories.
In March 1940 they had the capacity to make (but NOT the orders):
400 3.7" AA guns a year
121 40mm Bofors a year
840 Field guns (25 pdr)
1900 AT guns (2 pdr)
24 Naval guns (4-6" by the looks of it)
2000 Mortars
6000 Bren
2500 Vickers
200,000 Rifles
50,000 pistols
10,500,000 "Gun ammo" all natures.
1,950,000 Mortar ammo
240,000 aircraft bombs
730,000,000 small arms ammo.
2,000 carriers
1,000 light tanks
10,000 depth charges
3,000 Naval mines
260,000 AT mines
1,000,000 grenades
In Feb 1942 torpedoes where added to the list at 520 a year.
Some interesting "cost of production" Jun 1942 Pounds:
Carrier, MG LP2.....1500
2 pdr at gun........1750
3.7 AA..............6000
25 pdr..............4500
Vickers MMG.........109
Bren................150
Rifle...............13
1000 rounds303 ammo.9.9
Bomb 250lb anti sub.24
3.7 shell fille.....7.5
25pdr shell filled..3.9
4.5" shell filled...4.7
4" shell filled.....10
6" shell filled.....27
Australian manufactured items were cheaper than UK for small arms and SA ammo but more expensive for AA/arty/Naval shells (largely due to the lack of orders and therefore inability to effectively mass produce).
Actual production figures for period Jun 1940 til March 1942 then Jun 1940-June 1942 (I.e. the second figure INCLUDES the first figure)
25pdr Field Gun...267.......459
25pdr HE..........238,448...608,942
