Australian supply notes
Common argon-family cylinder sizes: D ≈ 1,700–2,000 L, E ≈ 4,000–4,600 L, G ≈ 8,700–10,200 L free gas — but always read your cylinder label, since volumes vary by supplier and fill pressure (BOC, Supagas, Coregas). Estimate your consumption with our gas flow calculator before choosing hire vs swap.
