Google Porters Palm Beach Black. Avail in Oz, works on most wood and is an amazing fab colour. I hope to use it on a project someday.

Look at 'Iron Ash'. Its a treated version of what you're after. Don't know anything about it but seen it recently on the web. Overall avoid Merbau as mentioned above, as well as being an imported 'sustainably' managed timber.... Use local product's when available as they're manufacturered to high standard's, supporting local job's, companies must meet tight regulation's, etc. unlike other countries....

I don’t have any practical advice but love the look. If you google images for Porters Paints Palm Beach Black you’ll see some great exterior inspiration.
