An elder shaliach, 82-year-old Rabbi Yitzchok Dovid Groner, founder of Chabad in Australia, has been hospitalized. Rabbi Groner had fluid on his lungs and required surgery to drain that fluid. He is recovering from that surgery and is expected to be released from the hospital this week.
For those in Melbourne, Rabbi Groner is not up to receiving visitors. The family asks all to say tehillim for Yitzchok Dovid ben Menucha Rochel.
Updates are posted by Chabad here.
Rabbi Groner is a direct descendant of the Alter Rebbe and, I'm told, one of the few truly learned men in Chabad.
