IECA AUSTRALASIA PRESIDENT’S MESSAGE

image
The past few months have been strong ones for IECA Australasia, with great momentum both internationally and here at home. I was proud to represent our chapter at the IECA International Annual Conference in Fort Worth, alongside colleagues from across the global IECA community. Our Australasia delegation was our largest yet, with 22 members attending, including our Young Professional scholarship recipients. The innovation, research, and practical solutions shared at the conference reinforced that our chapter continues to sit in a very strong position when it comes to best practice, education, and leadership in erosion and sediment control (ESC). My thanks again to Jerry Sanders, IECA President, and Samantha A. Roe, IOM, IECA CEO, for their ongoing leadership and support of our global community.
 
Back home, I'm extremely proud to be involved in practical, field‑based learning at our demonstration sites. The completion of the Hawkesbury ESC training facility in 2025, developed with Turf NSW and supported by research collaboration with UNSW, has given the region a purpose‑built site focused on real‑world applications. The last two successful field days at Hawkesbury have helped participants better connect design intent with what actually works on site. In Queensland, the Redlands ESC Demonstration Site again hosted a highly successful (and sold out) field day in March 2026, with live test plots, drainage controls, rainfall simulator, innovative koala fence and sustainable ESC and stockpile management demonstrations.
 
The relevance of our industry  has been clearly highlighted by significant rainfall, flooding, and cyclone impacts across the nation this last season. These events are a timely reminder of just how critical in areas that we work,  good ESC design, installation, and maintenance are in protecting communities, infrastructure, and waterways during extreme weather. They reinforce why consistent, best‑practice ESC is not optional or region specific—and why the training, field days, and knowledge‑sharing delivered through our IECA community are more important than ever.
 
Looking ahead, we’re focused on keeping this momentum going. Planning is underway to expand training and demonstration opportunities into Victoria, ACT, and New Zealand, and we’re ramping up for the IECA Australasia Conference in Sydney. Just as importantly, I encourage members to get involved beyond attending events—our sub‑committees play a vital role in shaping training, conferences, technical guidance, and industry engagement. If you’re passionate about education, best practice, young professionals, or industry collaboration, I strongly encourage you to put your hand up and join a sub‑committee. Your involvement is what keeps our chapter strong, relevant, and moving forward.

Kind regards
Dallas Frazier
President
IECA Australasia

NZ update - by Chris Wilcox

Hi all you Erosioneers!

Keeping this short and sweet, it feels like this year has disappeared as we are already past the first quarter and rapidly heading towards the winter season! For us in NZ I have already seen Regional Councils sending out comms regarding winter earthworks with applications required next month. Get on to them sooner rather than later to ensure your approvals come through in time.

There are a couple of events that erosioneers may be interested in. The next GD05 Community of Practice will be held May 1st in Auckland. This is an excellent forum focussed on ESC with learnings and updates across the industry. The Civil Contractors New Zealand Conference will be in Wellington 12-14th August, another great conference for people who deal with the earthworks doers.

A quick shout out to Mud Matters, an NZ focussed erosion and sediment control newsletter that has just released issue 1! If you are interested in NZ focused content from a passionate group of people, see the registration link below. Bonus points if you are keen to submit an article, innovation, learning or anything else.

Strong Start to 2026: ESC Training Field Days Drive Skills and Community

It’s been a busy start to the year, with two ESC training field days already completed—one at the NSW ESC Demonstration site and another at Redlands, Qld. Both events attracted strong participation, though the weather at each location was markedly different. In Richmond, NSW, we managed to dodge rain showers, while in Redlands the day was hot (over 30°C) and humid but remained dry.
Participants experienced live demonstrations in the test plots, observed operational controls in a working drain, and learned about sediment basins, as well as effective and ineffective methods for managing stockpiles and fertiliser test plots.

Key learning outcomes included:
  • Gaining hands-on experience with various erosion and sediment control (ESC) techniques through live demonstrations and practical observation of test plots and control measures.
  • Developing skills to distinguish between effective and ineffective ESC practices by comparing real-world examples, such as stockpile management and sediment basin performance.
  • Understanding the latest advancements and best practices in ESC, including insights from fertiliser trials, to enhance compliance and environmental outcomes on construction and development sites.

We extend our sincere thanks to Dallas Frazier for championing both days, Jenny Zadro (Turf NSW), and the LLS team at the Demonstration Farm for their extensive support preparing the site and assisting during the Richmond event. Special appreciation goes to Butch Uechtritz for stepping up to introduce ESC due to Dallas’ flight delays, and to Mark Stidwill and the DuraVeg team for their help with site preparation and coordination at Redlands.

Thank you as well to our sponsors—Envirostraw, | Vortec | Vital Chemical | B&K Revegetation | HL Landscapes | Australian Concrete Mats, and The Advanced Group—whose generous support helps keep registration fees affordable.

These events truly highlight the strong community within IECA, united in our commitment to improving the environment and supporting each other.

If you missed these training days, be sure to register for our upcoming sessions: 14th May in Richmond (registrations are open) and 9th July in Redlands (save the date).

" From Catchment to Coast, Erosioneers Unite for a Sustainable Future "

The 2026 IECA Australasia Conference & Expo will be held at the prestigious Shangri‑La Hotel in The Rocks, Sydney. This annual event brings together scientists, engineers, consultants, academics, suppliers, contractors, regulators, and practitioners from across Australasia with a shared commitment to protecting and restoring our vital soil and water resources.


Attendees will explore emerging research, industry innovations, practical case studies, and the essential lessons that guide effective land and water management. With a dedicated Exhibit Hall, multiple networking events, and a rich technical program, the 2026 conference promises outstanding opportunities for sponsors and exhibitors to connect with decision‑makers and industry leaders.

Hydromulching Standard - coming soon. by Michael Frankcombe

Hydromulching is everywhere, but not all “green spray” is created equal.

Do you know the difference between hydroseeding, standard hydromulch, bonded fibre matrix (BFM) hydromulch, fibre reinforced matrix (FRM hydromulch), and emerging biotic soil media solutions? More importantly, do you know when each should (and shouldn’t) be used?

IECA’s upcoming IECA Australasia Hydromulching Standard cuts through the confusion. Designed for practitioners, designers, specifiers, and regulators, it clearly defines product classes, performance expectations, and application contexts so you can make defensible, outcome-driven decisions on site.

If you’ve ever questioned why some applications establish quickly while others fail, this document will change how you specify, procure, and verify hydromulching works.

Coming soon, bringing clarity, consistency, and accountability to hydromulching practice.
