This batch adds official Federal Court explainers for related-party asset transfers before liquidation and payroll-tax unfair preference recovery. The practical theme is insolvency evidence discipline: sale processes, valuations, payment plans, tax arrears, related-party dealings and creditor communications need to be recorded before a later liquidator, creditor or court has to reconstruct them.
Small businesses can now browse the core federal laws behind GST, ABNs, BAS/PAYG administration, income-tax records and fringe benefits in one operational compliance topic.
