One consequence of the enclosed quarterdeck concerns the management of garbage onboard Perth. Having lost this large open ventilated space, and not wanting to simply clutter up the waist with numerous wheelie bins, ANZAC Systems Program Office installed a complete garbage management system. This system requires the absolute cooperation of all ships company, as all four types of waste must be separated at point of origin, whilst any food waste containers must be thoroughly cleaned before being placed in bins awaiting compaction. Paper and plastics are shredded and baled into ‘bricks’ which are then easily stored until the next ditching opportunity, whilst glass and metals are shredded and stored in up to 16kg ‘biscuit’ tins. Whilst being manpower intensive, the system does enable an FFH to retain garbage onboard for over 30 days if being tasked to remain within an environmentally sensitive area such as the Great Barrier Reef Marine Park.
