Recently revised figures for April show that the country’s trade deficit with the rest of the world ballooned to a record A$4.14bn (£2bn). That gap between the value of exports and imports is expected to increase as the value of Australia’s most important resources reaches new multi-year lows. Iron ore is now trading at around $50 per tonne, compared with a peak of around $180 per tonne achieved in 2011. Thermal coal has also suffered heavy losses, now trading at around $60 per tonne compared with around $150 per tonne four years ago.
