Weeds
A weed is a plant that establishes itself outside its normal environment. There are over 80 Declared Noxious Weeds in the Goulburn Broken Catchment. Noxious weeds are proclaimed under the Catchment and Land Protection Act 1994 and are classified in four categories each with different responsibility for management.

Under the Catchment and Land Protection Act 1994, it is an offence (without a permit) to buy, or offer to buy, sell, or offer to sell, possess for the purpose of sale, willfully bring or cause to be brought into Victoria, a noxious weed, noxious weed seed or any part of a noxious weed capable of growing. For further information or to report a possible sighting of a Declared Noxious Weed please contact the Department of Environment and Primary Industries (DEPI).



The Catchment and Land Protection Act 1994 (“CaLP Act”) was amended on 18 November 2013 resulting in the introduction of a new system of roadside weed and pest management.

The Catchment and Land Protection Amendment Act 2013 (“Amending Act”) has introduced a new system whereby municipal councils are required to prepare a roadside weed and pest animal management plan for land in their municipal district that is the subject of a declaration published in the Victoria Government Gazette.

On the occurrence of the declaration, the particular council, mentioned in the Gazette will be responsible for the implementation of the approved plan for the period of the plans operation, which will be between 2 and 4 years depending on the requirements of the relevant declaration. The roadside weed and pest animal plans are only required to address regionally prohibited weeds, regionally controlled weeds and established pest animals on rural municipal roads.

The amendments to the CaLP Act respond to recommendations made by the Roadside Weeds and Pest Animals Working Party, established in 2010 to review the existing system. The amendments are intended to clarify the system in relation to roadside weed and pest control. The old system being that adjoining landowners were responsible for managing most noxious weeds and established pest animals on roadsides, whilst the Secretary to the Department of Environment and Primary Industries and municipal councils might also have responsibility depending on the category of weed and whether the roadside land is Crown land or land vested in the municipal council.

The Catchment and Land Protection Act 1994 specifies four categories of noxious weeds in Victoria. These are; State Prohibited, Regionally Prohibited, Regionally Controlled and Regionally Constricted.

State Prohibited Weed
These weeds either do not yet occur in Victoria but pose a significant threat if they invade, or are present, and do pose a serious threat and that it is reasonable to expect that they can be eradicated from Victoria. Control of these weeds is the responsibility of the Department of Primary Industries wherever they occur throughout Victoria.

Regionally Prohibited Weed
Declared noxious weeds that are not widely distributed across Victoria, but are capable of spreading. It is reasonable to expect that they can be eradicated from a region. Private landholders are responsible for control on private land but not on roadsides adjoining their property, which are the responsibility of the Department of Primary Industries or Vic Roads, depending on the class of road.

Regionally Controlled Weeds

Declared noxious weeds that are widespread and established in a region. To prevent their spread, continuing control measures are required. Landholders have the responsibility to take all reasonable steps to control and prevent the spread of these weeds on their land and roadsides that adjoin their land.

Restricted Weeds

This includes plants that are a serious threat to primary production, Crown land, the environment or community health in another State or Territory of Australia, which have the potential to spread into and within Victoria, and pose an unacceptable risk of spreading in this State or to other parts of Australia if they were to be sold or traded in Victoria. Trade in these weeds and material containing them is prohibited.

The Integrated Pest Management System (IPMS) is a networked corporate business application owned by the Department of Environment and Primary Industries and operated and supported on its behalf by DEPI CAS Landscape Protection Branch.

IPMS is intended to support the management of strategically significant pest plant and animal infestations within the context of the Victorian Pest Management – A Framework for Action. It does not attempt to describe the full extent, density and distribution of pest plant and animal infestations in Victoria. The sites inspected may vary from year to year.

The State of Victoria does not warrant the accuracy or completeness of information in this publication and any person using or relying upon such information does so on the basis that the State of Victoria shall bear no responsibility or liability whatsoever for any errors, faults, defects or omissions in the information.



The Goulburn Broken Invasive Plants and Animals Strategy (IPAS) was developed by the Goulburn Broken Catchment Management Authority (GBCMA) with the aim of including pest plant management in integrated catchment management in the Goulburn Broken Catchment Region. Weed Management is acknowledged as a key factor by the GBCMA to improving the health of environmental conditions in the Catchment. The strategy provides a regional approach to weed management that complements the existing directions in the Australian Weeds Strategy and the Victorian Invasive Plants and Animals Policy Framework (IPAPF)..


The strategy endeavours to actively involve; public land managers, private land managers, local government, water authorities, infrastructure agencies and community groups.

The strategy aims to:
  • Identify priority areas for weed control programs to focus limited resources more strategically
  • Protect threatened assets, such as agricultural industries and biodiversity
  • Establish regional priority weed species
  • Encourage community ownership of weed program priorities
  • Clearly identify roles and responsibilities for all land managers
  • Provide a framework for investment on public and private land
The GBCMA have developed an identification Booklet for Weeds of the Goulburn Broken Catchment. To download a copy click here


Weed Spotters is an initiative of the Weed Alert Rapid Response Plan Victoria. Weed Spotters are members of the community who volunteer to assist the Department of  Environment and Primary Industries (DEPI) to monitor and report the number of serious potential, new and emerging weeds in Victoria.

Weed Spotters do not need to have botanical training, a keen interest and eye for plants is all you need. The DEPI will assist you by providing training in the identification of target weeds and how to report them. Weed Spotters who attend training receive a kit containing information to assist in the identification and collection of weed specimens and a quarterly newsletter.

If you are interested in further information or become a Weed Spotter click here.


Weed Warriors is a national program that is focused on educating school students from grade 3 to grade 9 about invasive pest plants with ‘hands on’ activities. The program is administered and supported by national and state/territory coordinators and is implemented at a local level by Key Contacts such as schools, community groups and individuals who have knowledge about and an interest in weed management.

For more information visit the Weed Warriors Website or call the Victorian Weed Warriors Technical Officer on (03) 9785 0111.


Current weed control projects implemented by Up2Us Landcare Alliance in the local area include:
  • Blackberry control program
  • Gorse control program
