BOM Water Market Data Standards

The BoM is progressing a new water trading information platform, reportedly costing $32.7 million, with a planned launch date of 1 July 2026. The platform is intended to provide “near real-time” water market information. However, members of the Australian Water Brokers Association are questioning whether the current design will deliver any meaningful improvement in market transparency, or whether it risks undermining the very outcomes it seeks to achieve.

Less information, not more

As outlined in recent media coverage, the BoM platform is expected to display bids and offers only, without publishing completed or settled trade data. This is a critical shortcoming. Many brokers already make traded price information available to the market, meaning the BoM website may ultimately offer less insight and less certainty than existing broker-operated platforms.

Without traded prices, bid and offer data alone risks being misinterpreted, particularly by less experienced market participants, and may provide a distorted view of market conditions.

Uneven obligations and market distortion

A further concern is the uneven application of reporting requirements across the industry. Brokers operating live matching exchanges will be compelled to supply pricing data from commencement, while others may not face similar obligations until July 2027, and only in limited circumstances.

This two-tiered approach risks:

• creating competitive imbalances between broker models;
• incentivising brokers to withdraw publicly available pricing information; and
• distortion of price signals, rather than further clarity.

Risk of reduced transparency

There is growing concern that the current approach could produce a perverse outcome: less publicly available market information than exists today. Faced with mandatory data sharing requirements and unclear benefits, some brokers may choose to cease publishing live or indicative prices altogether.

Such an outcome would run counter to the stated objectives of the reforms and could push trading activity away from transparent, well-established channels.

AWBA’s position

AWBA has consistently supported sensible, well-designed reforms that genuinely improve market confidence and transparency. However, as raised in our recent submission to the Water Amendment Regulations 2026 and Water Marked Data Standards Exposure Draft, the Association remains concerned that the current implementation of the BoM platform and data standards:

• places significant compliance and cost burdens on brokers;
• fails to clearly demonstrate tangible benefits for irrigators or investors; and
• risks weakening, rather than strengthening, the quality of information available to the market.

AWBA acknowledges the complexity of developing national data standards, but complexity alone does not justify outcomes that may reduce transparency or create unintended market distortions.

What members should consider

Members should remain alert to:

• how and when reporting obligations will apply to their business model;
• potential changes to pricing publication practices; and
• the commercial and compliance implications of participating in live matching environments.

AWBA will continue to advocate strongly on behalf of members and engage with government and the BoM to push for practical changes that deliver real transparency, consistent obligations and clear public benefit.

Further updates will be provided as the regulatory framework continues to evolve.
