Wet Harvest Disrupts Australian Macadamia Crop, Tightens Premium Kernel Availability
Prolonged rain in key Australian macadamia regions disrupts harvest logistics and trims exportable supply, with potential upside for kernel prices.
Persistent wet weather during harvest in northern New South Wales and parts of south‑east Queensland is disrupting Australia’s macadamia crop, delaying orchard access, increasing quality risks and tightening availability of premium exportable kernels. While global macadamia production continues to expand, near‑term supply from Australia’s key origin looks increasingly uneven, with traders already flagging firmer offers for top grades.
The latest Australian industry forecast has already been revised down to 56,888 tonnes in‑shell at 3.5% moisture for the 2026 season, from an initial 59,080‑tonne estimate, after field assessments highlighted weather‑related issues and slower progress in southern growing regions. Harvest is well advanced in Bundaberg under relatively favourable conditions, but prolonged rainfall has delayed picking and heightened quality losses where nuts remain on the ground in the Northern Rivers, Gympie and Glass House Mountains districts.
Introduction
Australian macadamias are predominantly grown along the eastern seaboard, with Bundaberg, the Northern Rivers of New South Wales and south‑east Queensland supplying the bulk of exportable volumes. Industry data point to a season of contrasts: solid yields and quality in Bundaberg versus waterlogging, orchard access constraints and quality downgrades further south.
For global nut buyers, the timing is critical. Australia is a key supplier of premium kernel styles into high‑value snack, confectionery and dairy‑alternative segments. Disruptions in one of the origin’s wettest harvests in recent years come as global production, led by China, South Africa and emerging African origins, continues to rise, keeping overall supply ample but increasing differentiation between high‑grade and standard material.
Immediate Market Impact
The main immediate impact is on grade distribution rather than headline tonnage. Prolonged ground time for fallen nuts in saturated orchards increases the incidence of mould, brown centres and pest damage, reducing kernel recovery and forcing more product into lower‑value industrial channels.
Exporters report that while aggregate in‑shell availability remains broadly adequate thanks to expanding plantings worldwide, the share of styles suited to premium retail snack lines is under pressure in weather‑affected Australian blocks. This is already reflected in a firmer tone for top kernel styles relative to bulk in‑shell and ingredient grades, even as global benchmark prices for standard macadamias stay historically competitive.

Supply Chain Disruptions
Heavy and frequent rainfall in the North Coast region has caused waterlogging and machinery access issues in orchards, slowing harvest and complicating post‑harvest drying. State seasonal updates highlight orchard management difficulties for macadamias under these conditions, with growers forced to wait for short weather windows to collect nuts, straining on‑farm storage and processing schedules.
At industry level, this creates an uneven shipping profile. Processors in Bundaberg, where harvest is about 90–95% complete under comparatively favourable weather, are closer to schedule, while northern New South Wales and parts of south‑east Queensland remain behind, leading to staggered container flows and sporadic availability of specific styles and sizes. This complicates vessel planning and may push some buyers to alternative origins for prompt coverage.
Commodities Potentially Affected
- Macadamia kernels (premium snack grades) – Higher reject rates from wet orchards and quality downgrades tighten supply of whole and large‑piece kernels destined for snack and confectionery use, supporting relative premiums.
- Macadamia kernels (industrial/ingredient grades) – Increased volumes of downgraded product may keep prices for small pieces and ingredient grades comparatively soft, enhancing their competitiveness versus other nuts in recipes.
- Competing tree nuts (almonds, cashews, hazelnuts) – Food manufacturers may respond to uneven macadamia grade availability by adjusting formulations, though current competitive macadamia pricing limits large‑scale switching in the short term.
- Value‑added macadamia products – Ice cream, bakery, snack bar and plant‑based dairy lines relying on consistent quality supply may face higher input costs or need to tweak specifications for upcoming production runs.
Regional Trade Implications
Australia’s weather‑affected harvest is likely to reinforce the shift toward diversified sourcing. China’s fast‑growing macadamia crop, forecast at 108,000 tonnes in‑shell in 2026, alongside rising South African volumes, offers buyers additional coverage, particularly for commodity‑grade kernels and in‑shell shipments.
However, Australia retains a strong position in premium markets in Asia, Europe and North America, where origin branding and quality consistency are valued. Importers targeting higher‑end segments may continue to prioritise Australian supply, accepting some shipment rescheduling or slightly higher offer levels, while price‑sensitive buyers, especially in emerging Asian markets, could pivot more heavily toward African and Chinese origins this season.
Market Outlook
In the short term, traders should expect continued volatility in availability by style and origin rather than an outright global shortage. As harvest concludes in the wetter southern regions and final crop numbers are confirmed, markets will gain clearer visibility on the split between premium and industrial grades from Australia.
With global plantings still maturing, structural supply growth for macadamias remains intact. Competitive prices are encouraging wider use in snacks and manufacturing, but current Australian weather disruptions underline the importance of diversified origin portfolios and flexible specifications. Attention in the coming weeks will focus on final Australian kernel recovery figures, shipping performance out of key ports, and early demand signals from major consuming regions as buyers position for 2027 contracts.
CMB Market Insight
The wet Australian harvest is a reminder that weather risk can quickly reshape grade balances and logistics in otherwise well‑supplied specialty nut markets. For macadamias, the immediate effect is a tightening of top‑end kernel availability from a premium origin, with potential support for differentials even as broader global supply expands.
Traders, importers and manufacturers should closely monitor Australian shipment programs and be ready to adjust origin mixes, forward coverage and product specifications. Those able to capitalise on temporarily softer ingredient‑grade prices while securing strategic volumes of premium styles are likely to be best positioned as the market digests this season’s uneven Australian crop.
