It's in the ALP rules, level 3-6 are judged out of 10 and have deductions halved on bars, beam and floor. Level 7+ are judged out of 10 for execution and have their difficulty added on (so at least 2.5 if they have full requirements) - most kids scores go up when they move beyond level six unless they have a shocker routine or don't belong in the level. Most are scoring above 10 in level seven which is not possible below level seven.
So yes a fall is still essentially a .5 deduction for low levels in Australia (unless it's vault). It was done so that judges didn't have to know two sets of rules while not discouraging developing gymnasts/families with really low scores.
