  • DUCK HUNTING in VICTORIA 2020 Background
    DUCK HUNTING IN VICTORIA 2020 Background The Wildlife (Game) Regulations 2012 provide for an annual duck season running from 3rd Saturday in March until the 2nd Monday in June in each year (80 days in 2020) and a 10 bird bag limit. Section 86 of the Wildlife Act 1975 enables the responsible Ministers to vary these arrangements. The Game Management Authority (GMA) is an independent statutory authority responsible for the regulation of game hunting in Victoria. Part of their statutory function is to make recommendations to the relevant Ministers (Agriculture and Environment) in relation to open and closed seasons, bag limits and declaring public and private land open or closed for hunting. A number of factors are reviewed each year to ensure duck hunting remains sustainable, including current and predicted environmental conditions such as habitat extent and duck population distribution, abundance and breeding. This review however, overlooks several reports and assessments which are intended for use in managing game and hunting which would offer a more complete picture of habitat, population, abundance and breeding, we will attempt to summarise some of these in this submission, these include: • 2019-20 Annual Waterfowl Quota Report to the Game Licensing Unit, New South Wales Department of Primary Industries • Assessment of Waterfowl Abundance and Wetland Condition in South- Eastern Australia, South Australian Department for Environment and Water • Victorian Summer waterbird Count, 2019, Arthur Rylah Institute for Environmental Research As a key stakeholder representing 17,8011 members, Field & Game Australia Inc. (FGA) has been invited by GMA to participate in the Stakeholder Meeting and provide information to assist GMA brief the relevant Ministers, FGA thanks GMA for this opportunity.

  • Local Context and Site Description
    LOCAL CONTEXT AND SITE DESCRIPTION Metropolitan and Regional Context The Greenvale Central Precinct Structure Plan (PSP) area is located approximately 20 kilometres north of the Melbourne CBD, within the Hume Growth Area shown on Plan 1. Melbourne‟s Hume Growth Area generally extends north from Somerton Road (west of Sydney-Melbourne rail line) to Gunns Gully Road at Merrifield. It includes parts of the suburbs of Greenvale and Craigieburn and the localities of Donnybrook, Kalkallo and Beveridge. The Hume Growth Area, along with the Mitchell and Whittlesea Growth Areas, make up the Melbourne North Growth Corridor. The Melbourne North Growth Corridor Plan details the strategic direction for future urban development within this region. The corridor is characterised by strong population growth occurring on various fronts. The population base is projected to increase from its current level of around 170,000 residents to over 220,000 people and has the capacity to provide for at least 68,000 jobs. The North Growth Corridor Plan provides an opportunity to establish new communities to assist in meeting Melbourne‟s urban growth needs over the next 30 years. The plan ensures that the following existing key roles and features are maintained within the Hume Growth Area: A strategic transport corridor of state and national significance; A gateway to Melbourne for interstate and international visitors; Large areas for future employment and industrial development; Highly self-contained working population (with approximately 50% of Hume‟s workforce employed within the municipality); Significant water catchments, creek corridors, remnant vegetation and stone resources on its east and west boundaries; and Important landscape features and biodiversity assets including grasslands and grassy woodlands.
