  • Known Impacts of Tropical Cyclones, East Coast, 1858 – 2008 by Mr Jeff Callaghan Retired Senior Severe Weather Forecaster, Bureau of Meteorology, Brisbane
    ARCHIVE: Known Impacts of Tropical Cyclones, East Coast, 1858 – 2008 By Mr Jeff Callaghan Retired Senior Severe Weather Forecaster, Bureau of Meteorology, Brisbane The date of the cyclone refers to the day of landfall or the day of the major impact if it is not a cyclone making landfall from the Coral Sea. The first number after the date is the Southern Oscillation Index (SOI) for that month followed by the three month running mean of the SOI centred on that month. This is followed by information on the equatorial eastern Pacific sea surface temperatures where: W means a warm episode i.e. sea surface temperature (SST) was above normal; C means a cool episode and Av means average SST Date Impact January 1858 From the Sydney Morning Herald 26/2/1866: an article featuring a cruise inside the Barrier Reef describes an expedition’s stay at Green Island near Cairns. “The wind throughout our stay was principally from the south-east, but in January we had two or three hard blows from the N to NW with rain; one gale uprooted some of the trees and wrung the heads off others. The sea also rose one night very high, nearly covering the island, leaving but a small spot of about twenty feet square free of water.” Middle to late Feb A tropical cyclone (TC) brought damaging winds and seas to region between Rockhampton and 1863 Hervey Bay. Houses unroofed in several centres with many trees blown down. Ketch driven onto rocks near Rockhampton. Severe erosion along shores of Hervey Bay with 10 metres lost to sea along a 32 km stretch of the coast.

  • Restoration of Noosa Estuary
    Ecological Service Professionals Sustainable Science Solutions Restoration of Noosa Estuary An Assessment of Oyster Recruitment Prepared by The Nature Conservancy & Ecological Service Professionals July 2015 Document Control Report Title: Restoration of Noosa Estuary: An Assessment of Oyster Recruitment Provider: The Nature Conservancy Contact: Edward Game [email protected] Acknowledgements This work would not have been possible without financial assistance from Noosa Shire Council and The Thomas Foundation. Important support was also provided by the Noosa Parks Association, in particular, we thank Brian Walsh who provided his vessel, skippered us safely around the estuary and provided such great company and assistance each day we ventured out in the field. The Walkers provided use of their jetty in Noosa Sound to suspend tiles, which was greatly appreciated. Executive Summary With the support of the Noosa Shire Council and The Thomas Foundation, The Nature Conservancy undertook an assessment of oyster recruitment in the Noosa Estuary. This assessment is a critical piece of information to inform the viability and design or future oyster reef restoration projects in the estuary. This report presents the findings of the assessment, which involved deploying over 160 settlement tiles (10 cm x 10 cm squares made from fibrous cement sheet) for periods of up to 5 months between December 2014 and June 2015. Settlement tiles were deployed at seven intertidal (0.1 m above low water mark) and five subtidal sites (typically 1 m below the surface) around the Noosa River Estuary. Key findings from the analysis of these settlement tiles are: Oysters recruited in moderate numbers at nearly all sites, with the highest observed recruitment occurring in Weyba Creek, the main channel around Tewantin, and in the narrow channel between Goat Island and Noosa North Shore.

  • 22Nd March 2019
    This booklet has been prepared to commemorate the historic 200th General Meeting of the Mary River Catchment Coordinating Committee on Friday 22nd of March 2019 at Garapine; the location of the inaugural meeting in November 1993. It adds to a previous booklet prepared for the 100th meeting which was held at the Gympie Civic Centre on Wednesday 16th February 2005. For almost 25 years, the MRCCC has forged productive partnerships with thousands of stakeholders throughout the Mary River catchment and beyond; government at all three levels, industry, farmers, large and small rural and urban landholders, landcare and environment groups, recreational and commercial fishing interests, forestry, irrigators, Waterwatch volunteers, researchers, school students, and particularly the long-running working partnership with the Gympie District Beef Liaison Group. These partnerships have triggered a phenomenal groundswell of interest and activities in natural resource management across the Mary River catchment. The wider community is beginning to understand many of the causes of environmental degradation. The farming community is embracing sustainable production as a means of increasing productivity whilst protecting natural assets. Governments at all levels now recognise that community engagement is critical to environmental repair and ecological protection. Triple bottom line objectives are now commonplace in strategic planning documents. So what were the factors that led to the need for an “across the board” shift in philosophy? In the 1990’s, the Mary River was described as one of the most degraded catchments in Queensland. European settlement resulted in extensive clearing of the riverbanks. In recent times, massive land use change due to subdivision, population pressure and other factors together with increasing demand for water resources led to deteriorating catchment condition.

Enquiries should be addressed to: Manager Publishing Services Queensland Department of Primary Industries GPO Box 46 Brisbane QLD 4001 Fisheries Guidelines for Design of Stream Crossings BACKGROUND Introduction Fish move widely in rivers and creeks throughout Queensland and Australia. Fish movement is usually associated with reproduction, feeding, escaping predators or dispersing to new habitats. This occurs between marine and freshwater habitats, and wholly within freshwater. Obstacles to this movement, such as stream crossings, can severely deplete fish populations, including recreational and commercial species such as barramundi, mullet, Mary River cod, silver perch, golden perch, sooty grunter and Australian bass. Many Queensland streams are ephemeral (they may flow only during the wet season), and therefore crossings must be designed for both flood and drought conditions.

  • Feedback on Draft Noosa River Plan Version 1
    General Committee Agenda 18 January 2021 Attachment 2 to Item 2 – Consultation Report River Plan Version 1 (2018) Feedback on Draft Noosa River Plan version 1 The information below provides a collation of detailed feedback on the Draft Noosa River Plan received from the community during the public consultation period from 20 July to 26 August 2018. This feedback consists of responses to the Noosa River Plan SURVEY published on Council’s Your Say Noosa (YSN) website, and written submissions received from individuals and organisations. Three questions were posed in the SURVEY: 1. What do you think will be most important in maintaining and improving the quality of the Noosa River system? 2. Are there any actions to consider for inclusion in the Draft Noosa River Plan? 3. The cost of implementing the actions recommended in the Draft Noosa River Plan is estimated to be $2.23M over 5 years (i.e. $446,000 pa). Are you willing to pay extra (via General Rates or Environment Levy and/or Tourism and Economic Levy) for Noosa Council to fully implement the River Plan so that the Noosa River has a better chance of remaining a pristine and vital community asset? If yes, how much per year ($5, $10, $15, $20)? Summary of feedback The top four (4) priorities deemed most important to maintain and improve the quality of the Noosa River system were identified as: • managing pollution and litter running into the river • protecting wetlands, riparian and coastal areas • reducing sediment from upstream entering the river • controlling recreational use of the
