Correct,
The log is a Marri ( Aussie blood wood) and useless for anything structural which is why old time millers didn't touch them and there are still many left especially on farms and ranches.

Not only shake but fist size pockets of blood red gum/resin as well

Despite these issues the timber has recently become fashionable even prized for use in furniture making.
From memory I only got about half a dozen what I would call decent slabs out of that log but was able to cut out the major cracks and gum pockets and got many smaller useful pieces from the rest - hard work.
Not all Marri is like this - younger/smaller trees can have solid wood in them some with real nice grain.

I used some of the wood from that log to make this wool drum carding machine for my wife.
I did all the stainless stee metal work as well.
