BGBL vs VGS: Is the Cheaper Global Shares ETF Worth the Switch?

For years, VGS was the default answer for Australians who wanted to own the rest of the developed world. Then in 2023 Betashares launched BGBL, a fund that does almost the same job for less than half the fee. Since then it has grown fast, and a common question has followed: should you use BGBL instead, and if you already hold VGS, should you switch?

The two funds are close enough that the answer mostly comes down to fees, track record and tax. Here is how they line up.

What each ETF holds

VGS

VGS tracks the MSCI World ex-Australia Index. At 30 September 2026 it held 1,219 large and mid-sized companies across more than 20 developed countries. About 74% of the fund was in the US, followed by Japan, the UK and Canada. We compared it with the US-only option in VGS vs IVV.

BGBL

BGBL tracks the Solactive GBS Developed Markets ex Australia Large & Mid Cap Index. That is a different index provider, but it aims to cover the same thing: large and mid-sized companies in developed countries outside Australia. It holds roughly the same number of companies, with the same giants at the top, such as NVIDIA, Apple, Microsoft, Amazon and Alphabet.

How different are the indexes?

Not very. The two index providers draw the line between "large and mid" and "small" companies in slightly different places, and they occasionally classify a country or company differently. The result is a small difference in the tail of very small holdings, while the bulk of the money sits in the same companies at almost the same weights. Over time you would expect their returns to stay very close, with the fee as the main gap.

BGBL vs VGS side by side

Returns are to 30 September 2026, after fees, with distributions reinvested. BGBL has not existed long enough to show three or five year returns. Past performance is not a reliable guide to future returns, and fund sizes change daily, so check each provider's page before investing.

Both funds are unhedged, which means their value in Australian dollars rises and falls with exchange rates as well as share prices. Our article on hedged vs unhedged ETFs explains what that means.

Fees: the main difference

BGBL charges 0.10 percentage points a year less than VGS. Here is what that means in dollars:

On $500,000, the gap is $500 a year. Because the money you save stays invested and compounds, a fee difference like this can add up to tens of thousands of dollars over a few decades for a large portfolio. When two funds hold almost the same things, the cheaper one has a built-in head start.

Track record and size

VGS: the long history

VGS has more than a decade of history and is one of the largest ETFs in Australia. Vanguard runs very large pools of money tracking the same index, and the fund has tracked its index closely for years. For some investors, that long, boring record is worth paying a little extra for.

BGBL: newer but already large

BGBL launched in May 2023, so it has a much shorter record. But it already holds around $5.5 billion, which is well past the size where everyday investors need to worry about the fund closing or trading poorly. Its one-year return to September 2026 was slightly ahead of VGS, which is about what you would expect from the lower fee.

A shorter history isn't a red flag on its own. With an index fund, what matters is whether it tracks its index tightly and cheaply, and there is nothing to suggest BGBL doesn't.

Should you switch from VGS to BGBL?

This is the real question for many investors, and the answer depends on tax more than fees.

Selling triggers capital gains tax

If you sell VGS units that have gone up in value, you make a capital gain, and part of it gets added to your taxable income for the year. If you have held the units for more than 12 months, you currently get a 50% discount on the gain, but it can still be a big bill. That tax can easily outweigh years of fee savings.

Here is a rough example for someone in the 30% tax bracket (plus the 2% Medicare levy, so 32% in total for 2026-27), sitting on a $40,000 gain:

At a $100 a year fee saving per $100,000, it would take many years of savings to make up that $6,400, and you would also lose the growth on the tax you paid. The numbers are different for everyone, and capital gains tax rules can change, so it's worth checking your own situation before you act.

A gentler approach

Many investors who prefer BGBL simply leave their existing VGS alone and send all new money to BGBL. Over time, BGBL becomes the larger holding without anyone paying tax to make it happen. If you ever need to sell units later, for example in retirement or in a low-income year, the VGS units can go first.

If your VGS units are worth less than you paid, or you hold them inside super or another tax-free setting, switching is much cheaper, and the fee saving becomes a stronger argument.

Who each one might suit

BGBL might suit you if

• You are starting fresh and want the lowest-cost broad developed markets ETF.
• You are building a low-cost Betashares pair, such as A200 with BGBL.
• You are happy with a shorter but solid track record.

VGS might suit you if

• You already hold it with large gains and don't want to trigger tax.
• You value a long history and one of the biggest funds in the market.
• You like keeping your portfolio with one provider, such as VAS with VGS.

How they fit into a portfolio

Either fund usually sits beside an Australian shares ETF. These examples show how the pieces fit, not what you should hold:

Conclusion

BGBL and VGS are close to interchangeable. They own about the same companies, in about the same proportions, with the same currency exposure. BGBL is cheaper, and VGS has the longer history.

If you are starting out, the lower fee is hard to ignore. If you already hold VGS, think about tax before you think about switching: directing new money to the fund you prefer is often the simplest way to get there. Either way, the most important thing is to keep investing regularly and leave it alone.
