Core and Satellite Investing in Australia

🛰️ What is a core and satellite portfolio?🔗

The strategy splits your investments into two parts. The core is a large, broad-market holding. It is diversified, low-cost, and designed to sit there doing its job without much fuss. Think of it as the engine of the portfolio.

The satellites are smaller positions around the edge. Each one expresses a specific view: a sector you believe in, a region you want more of, an income tilt, or a theme you want to follow. They are deliberate add-ons, not the main event.

🎯 The essential: The structure is popular with Australian DIY investors because it gives you both discipline and flexibility. You get the low cost and wide diversification of a passive core, plus a small, ring-fenced allocation to act on a conviction.

🧠 Why investors use this strategy🔗

The core does the heavy lifting. A broad-market ETF keeps your costs low, your diversification wide, and your returns close to the market. You are not trying to beat the market with the bulk of your money.

The satellites give you something to do, and that is not a trivial point. One of the biggest behavioural risks in investing is tinkering with a perfectly good portfolio out of boredom or fear of missing out. Giving yourself a small, contained allocation to express a view can actually protect the core by channelling that urge somewhere safe.

It also suits investors who have a genuine conviction about a theme, region, or style but do not want to bet everything on it. You can hold a tech or emerging-markets satellite without those positions dominating your outcomes.

📐 How to size your core and satellites🔗

Here is a simple illustration on a $10,000 portfolio: $8,000 (80%) in a broad diversified ETF as the core, and $2,000 (20%) split across one or two targeted satellites. This is an illustration only. The right split depends on your goals, risk tolerance, and time horizon.

What matters is that you decide the split before you buy anything. Write it down. Stick to it.

🌍 Core ETF examples for Australians🔗

The core should be broad, low-cost, and set-and-forget. There are two common approaches.

Option 1: a single diversified fund. One ETF that holds everything, then you add to it over time. VDHG (Vanguard Diversified High Growth ETF) is roughly 90% growth and 10% defensive across Australian and global shares plus bonds. DHHF (BetaShares Diversified All Growth ETF) is 100% shares across Australian and global markets at a low cost. Both are genuinely excellent core options for investors who want simplicity. See our VDHG guide for a deeper look.

Option 2: a two-fund combo. Combine VAS (Australian shares) with VGS (developed international shares), which lets you control the Australia versus international split yourself. The trade-off is that you decide and maintain that split. Our simple portfolio guide walks through how to build around either approach.

🎯 Satellite ETF examples🔗

Satellites should be deliberate. Each one should have a clear reason for being there. See our guide on how many ETFs to own before you start adding. Here are common satellite categories Australian investors use, with examples.

None of these are recommendations. They are examples of the types of satellite ETF that Australian investors commonly use. Always read the product disclosure statement before investing in any ETF.

⚠️ The honest risks🔗

This strategy has real downsides, and it is worth being clear-eyed about them.

Satellites can drag your returns. Most actively tilted positions underperform a broad market index over long periods. Your thematic or sector bet might look great for a year and then sit flat for five. That is common, not unusual.

More holdings mean more complexity. Every additional ETF is another line in your tax records, another position to rebalance, another brokerage cost when you buy or sell. That complexity compounds over time.

Fear of missing out is a genuine risk. The temptation to add a new satellite every time a theme hits the headlines is real, and chasing themes is one of the most reliable ways to buy high and sell low. Each new satellite should clear a high bar.

Many investors are better off with just the core. A single diversified ETF, held consistently over many years, will outperform most satellite-heavy portfolios after costs. That is not settling. It is a genuinely strong strategy.

🥊 Core and satellite vs one fund🔗

The core and satellite strategy suits investors who want some expression of a view but still want a disciplined base. It works best when the satellite allocation is small, deliberate, and reviewed regularly.

A one-fund portfolio (VDHG, DHHF, or similar) is simpler, cheaper to run, and often performs just as well or better after costs. There is no rebalancing between holdings, no temptation to tinker, and no extra tax complexity. Neither approach is universally superior. The right choice depends on whether you have a genuine, long-term conviction to express, and whether you have the discipline to keep satellites small. If you are not sure, the one-fund approach is a sensible default. See our simple portfolio guide for more on that path.

🧭 How to keep it disciplined🔗

The strategy only works if you stick to it. The habits that matter:

• Set your allocation in writing before you buy. Core 80%, satellites 20%, for example. Make it concrete.
• Limit satellites to a fixed number. Two or three maximum is a reasonable ceiling for most investors.
• Rebalance once or twice a year, not on every market move. Frequent rebalancing adds cost and encourages emotional decisions.
• Before adding any satellite, ask whether you would hold it for 10 years. If the honest answer is no, do not buy it.
• If a satellite no longer fits your thesis, exit it cleanly. A position you no longer believe in is just clutter.

Core and satellite is a framework, not a licence to keep adding ETFs. Discipline is the whole point.
