Investment Strategy and ETF Allocation Guidance

Superannuation has considerable tax benefits over investing in your own name, so don’t forget an allocation to that. Money you need prior to when you can start drawing super (60) is what you want in your own name. e.g. buying a house or drawing down on between early retirement and age you can access super.
My understanding is that VDHG is going to be duplicating many of your other holdings, so be aware of this.
If you are in accumulation, pearler automation does a wonderful job of getting to your allocation over time, and there is no selling required which is just additional cost. If the market throws a hissy fit over emerging markets causing your allocation to drop, then next purchase will buy them at the discount the market has presented for you.

To me this looks like you might be overcomplicating things a bit.

There is considerable overlap between VGS (mostly US shares), VDHG (mostly US), and NDQ (solely US).

There is also overlap between VHY and VAS.

In reality, there’s no need for all these holdings, and then doubling up on some of the biggest US companies individually.

The most common portfolios I see with holdings like that are VAS/VGS/VGE, or VDHG by itself. It can be reasonable to add other things, but make sure they’re actually adding something unique like companies you don’t already own inside these funds (which will be difficult given they cover the entire world already).
