Woolworths Group Ltd (ASX: WOW) has not been the easiest ASX share to own recently.
Supermarket investing can look simple from the outside, but the reality is more demanding. Customers want value, suppliers want fair prices, regulators are watching, costs keep moving, and competition does not disappear.
Even so, I think Woolworths could be a smart defensive buy for investors looking ahead to FY27.

A business built around repeat decisions
The appeal of Woolworths starts with frequency.
Most households do not think about groceries as an investment theme. They just keep buying them. Week after week, people need food, cleaning products, personal care items, pet supplies, and household essentials.
That repeat demand gives Woolworths a strong base.
The company has a large store network, a major online presence, loyalty data, supply chain scale, and relationships with millions of customers. That gives it many ways to improve the shopping experience, manage stock, personalise offers, and make the weekly shop easier.
I think that customer connection is valuable.
In retail, small gains can matter. A better app, a faster delivery slot, fewer out-of-stocks, sharper pricing on key items, or a cleaner store experience can all influence where people spend their grocery budget.
Defensive does not mean effortless
Woolworths still has plenty of work to do.
Grocery retail has become politically sensitive because households are under pressure. The company needs to balance margins, customer trust, supplier relationships, staff costs, and investment in stores and technology.
That is a difficult balance.
But I think the best defensive businesses are not the ones with no challenges. They are the ones with enough scale, relevance, and cash generation to keep working through them.
Woolworths has those qualities.
It also has a place in the economy that should remain important regardless of market mood. People may delay a holiday, a new appliance, or a home renovation. They still need groceries.
Why I'd consider buying Woolworths shares
For investors, the question is whether Woolworths can turn its defensive position into acceptable long-term returns.
I think it can.
The company does not need to become a high-growth technology stock. It needs to keep earning customer trust, improve productivity, use data well, invest in online and store operations, and return cash to shareholders over time.
That may sound unexciting, but it can be valuable in a diversified portfolio.
Woolworths can provide a different kind of exposure to the ASX. It is linked less to commodity prices or banking margins and more to everyday household spending. That can make it useful when investors want stability.
Foolish takeaway
Woolworths is not a perfect business, but I think it remains a useful one.
The company sits close to Australian households, has scale that few retailers can match, and operates in a category where demand keeps returning. In FY27, that kind of resilience could be appealing if investors remain nervous about the economy.
The investment case is about owning a business that can keep serving customers, generating cash, and adapting to a tougher retail environment. For investors wanting a defensive ASX share with long-term relevance, I think Woolworths is worth considering.
