3 ASX dividend shares offering gross yields of 8% or more

Don't just look for fat yields today, find shares that can keep cash flowing tomorrow.

Looking for solid income doesn't mean settling for a measly term deposit. Plenty of ASX dividend shares hiding in plain sight are quietly throwing off serious cash yields. And once you factor in franking credits, these shares could start looking hard to ignore.

Here are three ASX dividend shares worth putting on the watchlist right now.

Fortescue Ltd (ASX: FMG)

Fortescue built its name on iron ore, not income. But make no mistake, this ASX dividend share can pack a serious punch.

The mining giant paid out $1.08 per share over the past year. With Fortescue shares trading around $16.72, that's a cash yield of roughly 6.5%. Not bad on its own.

Here's the kicker: those dividends are fully franked. Gross that up, and the yield jumps to about 9.2% — the kind of number that makes bank hybrids look boring.

But don't get too comfortable. Fortescue's profits swing hard with iron ore prices, and so does its ability to keep writing dividend cheques this size. This ASX dividend share is a high-octane bet, not a set-and-forget income play.

Bendigo and Adelaide Bank Ltd (ASX: BEN)

Want banking sector income without piling into one of the Big Four? This ASX dividend share deserves a look.

Bendigo and Adelaide Bank's recent payout of 63 cents translates into a cash yield of around 6% at current prices. Add in franking credits, and the grossed-up yield pushes above 8%.

It's not a risk-free ride, of course. Interest rates, bad debts, competition and capital requirements can all squeeze bank earnings and dividends when the cycle turns. Still, for investors hunting franked income outside the usual Big Four suspects, this ASX dividend share earns its spot on the radar.

AGL Energy Ltd (ASX: AGL)

AGL has spent years reinventing itself, but its dividend is still the reason plenty of income investors keep watching.

The energy giant's FY2026 payout totalled 50 cents per share, including a fully franked 26-cent final dividend. At around $8.45 per share, that's a cash yield of roughly 5.9%. Gross it up for franking credits, and the yield climbs to approximately 8.5%. And we have another entry on the list of ASX dividend shares punching well above the headline number.

Management is targeting a 55%-60% payout ratio for FY2027, with dividends expected to stay fully franked, that's always subject to performance and board discretion.

Foolish takeaway

These three ASX dividend shares prove why income investors shouldn't stop at the headline cash yield. Franking credits can transform an average payout into a genuinely compelling one for Australian shareholders.

But a big number is only half the story. Fortescue's dividend rides on iron ore prices, Bendigo Bank's rides on the banking cycle, and AGL's rides on a rapidly shifting energy market.

The real prize isn't just finding ASX dividend shares with fat yields today — it's finding the ones that can actually keep the cash flowing tomorrow.
