The short answer is yes. A similar investigations, but not for baby food specifically, was done in 2015 by Food Standards ANZ Survey of tinned fruits for tin, lead and arsenic .
Their summary of findings are:
Are the small amounts of lead and tin found harmful?
No. The levels found in the FSANZ survey were well below the Maximum Level (ML) specified for lead and tin in the Food Standards Code. The MLs for metal contaminants are set to protect public health and safety and as low as practical based on sound production and natural resource management practices.
The results of this survey are also consistent with the Australian Total Diet Study (ATDS). which regularly tests Australian foods for levels of metals including lead, arsenic and tin, and has not identified safety concerns for consumers.

There were lots of references for America, but I could not find any references specific to ‘heavy metal contamination of baby food’ in Australia.
