REC315-3848 | 17 - Assets and technology | That, in order to enhance NSW’s ability to improve situational awareness, Government expand FRNSW’s Remotely Piloted Aerial Systems (RPAS) capability (both capital assets and trained operators) to major regional centres and ensure the NSW RFS and other NSW government agencies can access this capability as required. |
REC315-3826 | 10 - Infrastructure | That, in order to maximise the protection of critical infrastructure in a bush fire, Australian governments revise the regulatory framework for the provision to government authorities of information about all critical infrastructure (public and private) including a possible change to compel the owners of critical assets to provide all needed metadata, updated annually, for appropriate planning, preparation and response for bush fire. This would include information about location, ownership, access, details of service the infrastructure supports, and fire treatments of building and surrounding zones. |
REC315-3804 | 32 - Doctrine, standards, and reform | That the NSW RFS Commissioner consult with the Fire and Rescue NSW Commissioner and other emergency services to develop a protocol in the event that simultaneous emergency events necessitate the re-allocation of resources while a Section 44 declaration is in place. |
REC315-3836 | 17 - Assets and technology | That, in order to ensure frontline personnel have appropriate personal protective clothing during bush fires: |
REC315-3818 | 26 - Research | That, in order to improve understanding of optimal hazard reduction techniques and their application in the landscape: |

Getting it to a high-level of quality requires: |
REC315-3844 | 32 - Doctrine, standards, and reform | That, in order to enhance fire fighting strategies in severe conditions, the NSW RFS implements the following in respect to backburning: |
REC315-3821 | 4 - Fire season preparation | That government agencies managing land (at all levels and through all agencies) be the best neighbours possible by considering their neighbours when undertaking activities related to bush fire preparation and having clear, two-way communication about these activities, with the aspiration that government landholders will be seen as highly desirable neighbours. |

The framework should: |
REC315-3815 | 17 - Assets and technology | That, in order to equip NSW RFS with comprehensive information on all structures and assets at risk of bush fire, Government ensures that: |
REC315-3843 | 17 - Assets and technology | That, in order to improve early fire suppression, the NSW RFS trial initial aerial dispatch in areas of high bush fire risk. The trial should identify the most appropriate and cost-effective mix of aircraft, and any associated infrastructure improvements that would be required. |

REC002-4011 | 32 - Doctrine, standards, and reform | The Commission feel that the 4th clause in the present Act, relating to the spacing of cut-throughs, should be amended to admit of any convenient or safe system of mining being pursued. This is a matter of detail that would be better out of the Act. The Commission would advise that the word should not occur at all, and that, if bratticing be used, or the air by some other satisfactory device be conveyed to the face, scope would be given to Managers to introduce systems of mining adapted to the circumstance of each particular coal-seam, with advantage to all concerned. |
REC002-4006 | 17 - Assets and technology | The Commisison would not insist upon a barometer being provided at each mine. Experience has proved that this is a tardy index to atmospheric conditions. Serious changes in the atmospheric pressure occur and are felt before they are indicated by a barometer. |

REC288-1192 | 32 - Doctrine, standards, and reform | The Committee finds that on the evidence presented, that section 107 of the Fire Service Act should be amended to provide greater clarity in relation to discretionary spending by the Chief Officer or alternatively, the Act should be amended to include the authorisation for the State Fire Commission to directly fund the State Emergency Service. |
REC288-1191 | 32 - Doctrine, standards, and reform | The Committee finds that on the evidence presented, that a review and reform of the Fire Services Act 1979 is necessary. An investigation should be undertaken to assess how the legislation can be amended or replaced to best service the organisations subject to the Act and should be undertaken and completed within 12 months. The Fire Services Act 1979 must be reformed or replaced to allow for: (1) A centralised funding model for the State Emergency Services; (2) Streamlined approach to fire fighting between Tasmania Fire Service, Tasmania Parks and Wildlife Service, Forestry Tasmania and other relevant agencies; (3) Resources to be allocated according to the risk and not according to local government municipal boundaries; (4) The continuation of Tasmania having a singular fire service; (5) Clear reporting lines; (6) Improved governance structure; and, (7) Include the fire permit system and inter- agency protocols. |
