EXCLUSIVE WET HARVEST BRIEFING

Rain doesn't wait for a claims assessor. Neither should your payout.

Wet Harvest pays out automatically when rain crosses your threshold during harvest — based on the Bureau's own numbers, not someone else's judgement of your paddock.

Jono's spent years studying how rain at harvest actually hits grain quality — including his own research at the University of Southern Queensland on rainfall's effect during the harvest window. In this video, he walks through a real worked example: a grower hedging $1,000,000 of downgrade risk on wheat, and exactly how the numbers come together.

HARVEST RISK & FIELD DATA

Why a Wet Harvest Costs More Than a Delay

Rain during harvest doesn't just cost you time on the header — it downgrades the grain itself, and the discount can be steep.

30–50%

Downgrade Range

Significant rain over a harvest window can discount wheat, barley, hay and other crops by 30 to 50 percent depending on severity — for noodle wheat and hay, a rain event can mean a straight 50 percent downgrade.

$108/t

The Milling-to-Feed Gap

A real Condobolin grower's 2022 wheat crop faced a swing from $360/tonne milling grade to $252/tonne feed grade — a $108/tonne gap on every downgraded tonne.

5–20%

Yield Loss from Delay

Before quality is even factored in, GRDC data shows harvest delays alone — through pod drop, shattering and lodging — can cost 5 to 20 percent of yield.

REAL GROWER PROOF

Already Worked, for a Real Grower

Jono's example shows how the maths works. Here's what it looked like when it happened for real.

$1.2M+

Total payouts banked across three harvests — 2021, 2022 and 2024 — for a Condobolin grower

$475,000

Single-season payout in 2022 alone — Condobolin NSW

3 seasons

Two different crops and three different wet seasons covered

A grower near Condobolin has used Wet Harvest cover for three harvests running — 2021, 2022 and 2024 — and banked over $1.2 million in payouts across two different crops and three different wet seasons, including $475,000 in 2022 alone.

Individual results vary by property, crop, cover selected and season — past payouts aren't a guarantee of future ones.

FORMULAS & ASSUMPTIONS

• Baseline Revenue = 1,500 t × $360/t = $540,000

• Downgraded Tonnes = 1,500 t × 30% = 450 t

• Revenue Loss = 450 t × ($360 - $252) = $48,600

• Rain Season Payout = max(0, 160mm - 100mm) × $2,000/mm = $100,000 capped at $100,000

• Rain Day Payout = max(0, 5d - 3d) × $15,000/day = $30,000 capped at $30,000

• Total Payout = $100,000 + $30,000 = $130,000

• Hedged Net = $491,400 + $130,000 = $621,400

The Wet Harvest Certificate combines two independent triggers (Rain Season + Rain Day). Biological grain downgrade loss is decoupled from the insurance payouts. Illustrative simulation only — not a quote or binding offer.

What This Isn't

A Wet Harvest Certificate pays what you agreed to when your thresholds were set — it isn't a loss adjuster's assessment of exactly what your downgrade cost you, because there isn't one. That's the trade-off, made deliberately: give up precision, gain speed and certainty. Once a payout's landed in 20 days instead of six months, most growers find it's the trade worth making.

WHY CELSIUSPRO PARAMETRIC COVER

The Relief of Certainty in an Uncertain Australian Climate

Traditional multi-peril crop insurance forces you through weeks of loss adjusters, field inspections, and tedious haggling. CelsiusPro changes everything with weather-triggered parametric technology.

01

No Claims, No Assessors

No case to build for your own loss in the middle of harvest, and nobody walks your paddock to decide how bad it really was. The Bureau's numbers decide, not a judgement call.

02

Automatic Payout in Under 20 Days

Cash lands while you can still do something with it — not six months after an indemnity claim finally clears.

03

Built Around Your Operation

Rain Day and Rain Season thresholds set to your crop, your harvest window and your risk — not a generic policy.
